- CT: CT is the imaging procedure of choice to evaluate diverticular disease, as it can show many aspects of disease that are not recognizable by other studies. For inflammation or abscess, helical CT with colonic contrast has a sensitivity and specificity of 97 and 100%. CT scan can assess complications better. Ultrasound: If the target diagnosis is an abscess, then ultrasound has a sensitivity and specificity of 97 and 98%.

- Her physicians suspected she had a brain lesion, and with Hounsfield's equipment they were able to see clearly a dark, circular cyst in her brain. Hounsfield called this technology a CT (computerized tomography) scan, also called a CAT scan (computerized axial tomography). It was especially useful for looking at head injuries and brain problems, because it showed about 100 times greater detail in soft tissues than traditional x-rays.

Top 40 Doctor insights on: Can A Sinus Ct Show Ear Problems Not very well: Ct techniques used to image the temporal bones or sinuses are tailored specifically to evaluate these areas. Only small portions of the brain are even included in the field of view. Also, the images are processed to give the best bony detail which makes the soft tissues difficult to evaluate.

-  Almost always, CTs ordered should be ordered “with” OR “without’ only – NOT BOTH.  A ‘with and without’ protocol is generally needed only for exams to assess hematuria, or. known masses of the liver, kidneys and pancreas.  CT of the abdomen and pelvis (with the exception of a CT stone study and CT angiography) will receive an oral contrast prep.  General survey exams for pain or other non-specific symptoms can be performed either. “with IV contrast only” or “without IV contrast only” but should not be “with and without”. as such a scan increases patient radiation dose and generally without added diagnostic. value. o Common indications that do not require the use of IV contrast: diverticulitis, hernia.

Clinical studyHeavily Calcified Occlusive Lesions of the Iliac Artery: Long-Term Patency and CT Findings After Stent Placement To determine the quality (ie, hardness) and quantity (ie, volume) of iliac arterial calcification, an interventional radiologist evaluated the axial images of the multidetector CT data set. Calcium scores were obtained according to the method described by Agatston et al (16).he purpose of this study was to evaluate the influence of heavy calcifications on iliac arterial stent expansion and deployed stent patency and to define the spatial relationship between the stent and heavy calcification on computed tomography (CT).

Computed tomography angiography Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used to visualize arterial and venous vessels throughout the body.TA can be used to examine blood vessels in many key areas of the body, including the brain, kidneys, pelvis, and the lungs. Under some circumstances the coronary arteries may be examined by CTA, but CTA has not replaced invasive catheter coronary angiography.

What are some features that help distinguish a picture of a CT scan from a picture of an MRI scan? A CT scan can reveal a tumor in the abdomen, and any swelling or inflammation in nearby internal organs. It can show any lacerations of the spleen, kidneys, or liver. As a CT scan detects abnormal tissue, it is useful for planning areas for radiotherapy and biopsies, and it can provide valuable data on blood flow and other vascular conditions. It can help a doctor assess bone diseases, bone density, and the state of the patient's spine.
