Non-Invasive Imaging Technology

Non-invasive imaging technology is a type of medical imaging that uses radiation, light, or ultrasound to generate images. It has many applications, including screening for cancer and other diseases early in the stage when it's most treatable, identifying abnormalities during pregnancy (including Down syndrome), and confirming the diagnosis of surgical procedures. Non-invasive imaging technology is also be used to track changes in biomarkers over time (including tumor size) or evaluate treatments including chemotherapy or radiation therapy.

Functions of Non-Invasive

Imaging Technology (NIIT)

Non-invasive imaging technology has many functions that benefit patients, including the detection and staging of cancer, monitoring treatments, detecting early signs of Alzheimer's disease or dementia, and assessing pain.

  • One of the most common uses for NIIT is in the detection and staging of cancer. By using computerized tomography (CT), magnetic resonance imaging (MRI), or ultrasound scanning technologies to scan patient tissues at various stages of development, doctors determine whether a tumor exists and how large it is. This information helps in making informed treatment decisions based on individual patient needs.
  • NIIT also plays an important role in the monitoring phase after surgery by helping doctors track recovery rates as well as assess changes over time from different types of treatments.
  • Additionally, image-guided radiation therapy is delivered more accurately when checked regularly against pre-treatment scans using NIIT technology.
  • Lastly, NIIT is often used to detect early signs or indications that someone might have Alzheimer's disease or dementia due to its ability to spot subtle changes including plaques or tangles within brain tissue. In 2022, 6.5 million Americans 65 and older are expected to have Alzheimer's. 75 years of age or older make up 73%.

Which Non-Invasive Imaging Technology is Best?

One of the most cutting-edge, non-invasive, and comfortable imaging modalities, MRI is only limited by high prices, staff qualifications, and incompatibility with ferromagnetic materials. The medical imaging technology, magnetic resonance imaging (MRI), generates detailed images of the body by utilizing powerful magnets and radio waves. MRI is used to detect conditions including tumors, cysts, strokes, brain injuries, and more. Most people undergo an MRI scan when they are scheduled for surgery to monitor their health over time. However, it also is used for non-medical purposes including detecting injury risk in athletes or monitoring pregnancy. Additionally, MRIs are becoming increasingly popular for treatments including weight loss surgery, regenerative medicine therapies, and targeted cancer therapy. MRI scans provide superior image quality due to the use of contrast agents and strong magnetic fields. This allows doctors to see details that aren’t visible with other imaging technologies including x-rays or ultrasounds. As per our analysis, in the United States, more than 34 MRI units were installed in the year 2020 for every 1 million people.

Non-Invasive Imaging Technology Types

There are many types of non-invasive imaging technology that are used to capture images of the body during medical procedures. Some examples include computerized tomography (CT), magnetic resonance imaging (MRI), and ultrasound.

  • Computerized Tomography (CT) - Computerized tomography is a type of X-ray that uses computers to create three-dimensional images of organs and tissues in the body. This diagnostic imaging equipment is often used to identify and monitor conditions including cancer, heart disease, stroke, brain abnormalities, and childbirth. CT scans are also helpful in diagnosing injuries and determining the extent of damage caused by those illnesses. A CT scan was conducted for every 1,000 people in the US in 2019 at a rate of around 279 scans. CT scanners use very small doses of radiation rather than huge amounts including traditional X-rays so they are less damaging to the body. Additionally, since CT scans are performed multiple times on a single patient without any negative side effects (unlike conventional radiographs), they're often preferred over X-rays for imaging patients who require frequent surgery or monitoring throughout their treatment journey.
  • Magnetic Resonance Imaging (MRI) - MRI is an image clarity alternative to CT that uses different radio frequencies and produces detailed pictures of structures inside the body, including bones, muscles, and blood vessels. MRI is a non-invasive technology that uses powerful magnets and radio waves to create detailed images of the body. This procedure is used to diagnose medical conditions, assess injuries, and detect abnormalities in the brain and spine. In 2021, the market for magnetic resonance imaging was estimated to be worth USD 4.8 billion. MRI is often considered one of the most accurate imaging technologies available today, as it produces pictures that are easily understandable by physicians and patients. Additionally, MRI scans are not affected by changes in humidity or temperature which makes them very reliable when it comes to detecting health problems. MRI scanners use 2D images or 3D models to produce these comprehensive pictures. While many people find this technology anxiety-provoking, it's important to remember that MRIs provide much-needed information for both doctors and patients.
  • Ultrasound - Ultrasound is a medical technology that uses sound waves to image the body. It is often used for various scans including fetal monitoring, breast exams, and cancer screenings. Ultrasound images are usually very clear and used to determine the severity of conditions or injuries. Additionally, ultrasounds allow doctors to see inside organs in more detail than other types of imaging procedures. There are many benefits associated with using ultrasound technology, including improved accuracy during surgeries and faster diagnosis times when compared to other methods. In addition, ultrasound help reduces pain and swelling after surgery by delivering medications directly into targeted areas without damaging surrounding tissue or nerves. 10.1% of ultrasound exams were carried out in the first trimester of pregnancy, followed by 57.0% in the second and 32.9% in the third.

Health Advantages of

Non-Invasive Imaging Technology

Minimally invasive & non-invasive medical imaging and visualization systems are increasingly being used in the healthcare industry to detect and diagnose conditions early. This is especially important for diseases including cancer, where early detection lead to better outcomes.

One of the most common uses of non-invasive imaging technology is topography mapping.

  • Topography Mapping - helps in assessing bone quality and measuring changes over time. Bone health has a significant impact on overall health and with this type of data, clinicians recommend preventative measures or treatments that improve the chances of long-term success. One of the most commonly used methods for topography mapping is ultrasonography, which uses sound waves to create detailed images of internal body structures. Other techniques include x-ray tomosynthesis and magnetic resonance imaging (MRI). By using these various technologies, healthcare professionals obtain highly accurate pictures of both soft tissues and bones. In May 2021, the average yearly salary for diagnostic medical sonographers was $77,740.
  • Vascular Assessment (Measuring Blood Flow) - A vascular assessment is an important tool that doctors and therapists use to assess the health of a patient's blood vessels. This involves measuring various factors, including arterial stiffness, flow-mediated dilation (FMD), and endothelial function. By assessing these parameters, doctors better understand how well the overall circulation is functioning and make recommendations for improvement. Vascular assessments are also used to diagnose conditions including atherosclerosis or stroke. Suspected claudication symptoms (89.3%), suspected rest discomfort (86.0%), and a history of diabetes (85.3%) were the three factors that were most often used to determine whether to undertake a vascular evaluation.
  • Brain Imaging (Mapping Nerve Damage) - Several different brain imaging methods are used to map nerve damage. Some of the most common include diffusion tensor imaging (DTI), magnetization transfer ratio mapping (MTM), and functional magnetic resonance imaging (fMRI). MTM is often used to detect changes in white matter connectivity, which is an indicator of nervous system health. MRIs are useful for detecting changes in neural activity, as well as measuring how active specific regions of the brain are during various tasks. According to the Brain, Development Laboratory, this raises the total number of participants to more than 1,000 and the number of individual scans to around 20,000.
  • Breast MRI (Detecting Abnormalities) – A breast MRI is a type of imaging that is used to detect abnormalities in the breasts. This includes tumors, cysts, lumps, and other conditions. Breast MRIs also help to determine if there is any damage caused by an inflammatory response to cancer treatments or previously detected disease. Benefits of having a breast MRI include early detection of diseases and problems, helping them make informed decisions about treatment options, and providing detailed information on the condition of people’s breasts. Additionally, this procedure allows for more accurate diagnosis and treatment planning for women who are diagnosed with cancer later on in their life. A breast MRI typically costs around $300-400 per session but represents one of the most cost-effective ways to obtain high-quality information about breasts.
  • Fetal Scanning (Evaluating Pregnancies) - Fetal scanning is a common procedure used to evaluate pregnancies for any number of reasons, including before conception, during early pregnancy, or at delivery. It involves placing an ultrasound transducer inside the mother's vagina and using it to view the fetus. This allows doctors to distinguish between normal growth and abnormalities in the baby's anatomy. Additionally, fetal scanning also is used as a diagnostic tool for risk factors including chromosomal syndromes or birth defects. In pregnancies that are more than 7 to 8 weeks along, ultrasounds sometimes pick up a fetal heartbeat.
  • Abdominal Ultrasound (tracking development during pregnancy) – Abdominal ultrasounds are a type of medical imaging that uses radiology devices utilizing high-frequency sound waves to create images of the inside of the body. This procedure is used to diagnose various conditions, including childbirth complications, gestational diabetes, and intestinal issues. Additionally, abdominal ultrasonography is used to screen for certain cancers including ovarian cancer and colorectal cancer. The whole population's prevalence of abdominal ultrasonography usage was 6.42% (5.94% for women and 6.91% for men).

Non-Invasive Imaging Technology Limitations

There are a few potential drawbacks to non-invasive imaging technology,

  • The most common of which are false positives. This means that devices incorrectly identify abnormal areas as being disease-free when, in fact, they are infected or diseased.
  • Additionally, this type of technology can be difficult to interpret and lead to unnecessary treatment if it is used inappropriately.
  • Other potential drawbacks include the discomfort associated with some forms of radiation therapy and possible side effects from certain imaging drugs.
  • Finally, there's always the risk of greater harm arising from using invasive procedures including surgery rather than alternative forms of imaging tech including scans or x-rays.
