"If we don't have symptoms, do we still need to do a whole-bodyMRI?"
According to recent statistics from our clinic, among the 115 asymptomatic patients who underwent whole-body magnetic resonance examination, 30 to 33% were classified as having tumors or suspected tumors requiring continuous follow-up. Their average age was 51 years old, with a higher proportion of women (71 patients) and men (44 patients). Among them, there were brain tumors, pancreatic tumors, lung nodules, large intestine lesions, prostatic hypertrophy, gynecological and head and neck problems. In addition, we have also discovered some diseases that require early attention, such as stroke, cerebral hemangioma, renal hemangioma, dry bones, cervical and lumbar degeneration, etc. It can be seen that whole-body MRI scans can detect hidden diseases lurking in the human body.
The advantage of magnetic resonance is that there is no radiation like computer scan (CT) orPositron Emission Tomography (PET)(PET/CT), but it can still help doctors understand and evaluate the condition and make treatment recommendations for patients. MRI is the abbreviation of "Magnetic Resonance Imaging" in English and "magnetic resonance" in Chinese. It is a non-invasive examination that uses high magnetic fields and radio waves to generate signals from the hydrogen nuclei (protons) in the human body. These signals are generated by computer calculations and displayed in the image.
MRI examination is suitable for most parts of the human body, including the musculoskeletal system and nervous system. MRI has high soft tissue resolution and is the first choice for examining the brain, nasopharynx, spinal nerves, intervertebral discs, muscles, joints such as the cruciate ligaments and menisci of the knee, and the pelvis.
Most patients are used to check for stroke, spine, cancer and other problems, and can detect lesions more effectively and earlier than CT. Brain MRI scans are effective in early stroke detection and vascular assessment. Spinal MRI scans can diagnose neck, back, and lower back pain and reveal bones, discs, spinal cord, and even narrow nerve channels. For tumor diagnosis and tumor staging, it can distinguish between normal and diseased tissues and help doctors evaluate cancer metastasis.
Unfortunately, patients with artificial ear sockets, older pacemakers, or claustrophobia may not be able to access MRI. In addition, CT is frequently used in areas of the body that lack water, such as the lungs, bones, and coronary arteries that require rapid technology. Of course, each patient should discuss it with his or her doctor and take into account the clinical symptoms to determine the best diagnostic method so that the patient can receive appropriate control earlier.
