Doctors are warning patients not to wear spandex clothing when coming in for a magnetic resonance imaging (MRI) procedure. Fabrics that use spandex often have metallic threads that could react ...
During the last 150 years, thousands of papers focusing on the effects or side effects of magnetic or radiofrequency fields have been published. They can be categorized as incidental and physiological. [2] Contraindications to MRI include most cochlear implants and cardiac pacemakers, shrapnel and metallic foreign bodies in the eyes.
Camptocormia is becoming progressively found in patients with Parkinson's disease. [4] The diagnosis of Parkinson's-associated camptocormia includes the use of imaging of the brain and the spinal cord, along with electromyography or muscle biopsies. Muscle biopsies are also a useful tool to diagnose camptocormia. Muscle biopsies found to have ...
Parkinson's typically manifests in individuals over 60, with about one percent affected. In those younger than 50, it is termed "early-onset PD". No cure for Parkinson's is known, and treatment focuses on alleviating symptoms. Initial treatment typically includes L-DOPA, MAO-B inhibitors, or dopamine agonists.

Symptoms for spinal tumors may vary due to factors such as the type of tumor, the region of the spine, and the health of the patient.

MRI contrast agents may be administered by injection into the blood stream or orally, depending on the subject of interest. Oral administration is well suited to gastrointestinal tract scans, while intravascular administration proves more useful for most other scans. MRI contrast agents can be classified [2] by their: Chemical composition
After age 50 or 60, osteoarthritic degeneration (spondylosis) or spinal stenosis are more likely causes of low back pain or leg pain. 4.8% of males and 2.5% of females older than 35 experience sciatica during their lifetime. Of all individuals, 60% to 80% experience back pain during their lifetime. In 14%, pain lasts more than two weeks.
