CT scanning

Sound waves and visible light are the waves used to clear a blockage from small tubes in the kidneys. The procedure through which the blockage is removed is called Shock Wave Lithotripsy (SWL).

An MRI may be able help identify structural lesions that may be pressing against the nerve so the problem can be corrected before permanent nerve damage occurs. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings.

Magnetic resonance imaging (MRI) and functional magnetic resonance imaging (fMRI) scans are the form of neural imaging most directly useful to the field of psychology.

• release of radiation and poor quality images.
• high cost and the need for shielding from the magnetic signals.
• can only view metabolically active tissues and inadequate availability of equipment.
• release of radiation and the need for a patient to be confined to metal tube for up to 30 minutes.

An MRI machine uses powerful magnets that can attract any metal in your body. If this happens, you could get hurt. It can also damage equipment that’s implanted in your body — a pacemaker or cochlear implant, for instance.

Worse, a large study in the US has shown that that getting a MRI early on in acute episodes of low back pain, even cases with nerve compression pain such as sciatica and controlling for severity and age led to significantly worse outcomes, such as $13,000 more in medical costs and more time off work – All by getting a …

The strong, static magnetic field of the MRI scanner will pull on magnetic materials and may cause unwanted movement of the medical device. The radiofrequency energy and magnetic fields that change with time may cause heating of the implanted medical device and the surrounding tissue, which could lead to burns.

CT Scan cost approximately half the price of MRI. MRI scan cost is comparatively higher than that of the CT scan.

For most musculoskeletal issues, MRI is the imaging procedure of choice. CT Head without contrast for initial evaluation of trauma/hemorrhage. MRI Brain with and without contrast for evaluation of infection, inflammation and neoplasm. If MRI contraindicated then a CT Head with and without contrast.

RESULTS: The overall sensitivity, specificity and diagnostic accuracy were 97%, 97% and 97%, respectively, for five studies in which scanning was performed with rectal contrast, and 83%, 95% and 92%, respectively, for two studies in which it was performed with oral contrast.

Doctors might order MRIs instead of CTs when they need to create more accurate and detailed images. Physicians typically order MRI scans to diagnose issues with bones, joints, and organs, especially those that affect the: Brain. Breasts.

CONTRAST MEDIA: CT scans are most frequently done with and without a contrast media. The contrast media improves the radiologist’s ability to view the images of the inside of the body. Some patients should not have an iodine-based contrast media.

The image shows your bones, organs, and soft tissues more clearly than standard x-rays. CT scans can show a tumor’s shape, size, and location. They can even show the blood vessels that feed the tumor – all without having to cut into the patient.

Radiography can detect fecal impaction and fecalomas in the colon and rectum however provides no sensitive or specific findings of stercoral colitis [3, 13, 14]. CT is diagnostic of stercoral colitis and its complications and can also exclude alternative causes of pain [3, 13, 14, 15].

Typically, CT focusing on vascular disease (e.g., aneurysm, dissection) or renal or pancreatic pathology may include noncontrast-enhanced images to identify calcifications. 20 Contrast-enhanced studies would be performed on the same day, in the same setting.
