A CT scan image showing a ruptured abdominal aortic aneurysm. CT Scan of 11 cm Wilms' tumor of right kidney in 13-month-old patient. Computed tomography of the abdomen and pelvis is an application of computed tomography (CT) and is a sensitive method for diagnosis of abdominal diseases. It is used frequently to determine stage of cancer and to ...
Computed tomographic (CT) gastrography, also called virtual gastroscopy (VG), is a noninvasive procedure for the detection of gastric abnormalities. Multiple X-rays are used to create a 3-Dimensional image of the organ, allowing abnormalities to be detected.
Non-contrast-enhanced CT scans are the gold standard for diagnosing kidney stone disease. [69] They allow clinicians to estimate the size, volume, and density of stones, helping to guide further treatment; with size being especially important in predicting the time to spontaneous passage of a stone.
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
2.5 cm on CT scans [21] [22] Mild: 2.5–2.9 cm [23] Moderate: 3-4 cm [23] Severe: >4 cm [23] 3 cm on abdominal X-rays [21] [24] (Projectional radiography confers a geometric magnification compared to CT [25]) Wall thickening: 3–5 mm [26] Spleen: Splenomegaly: Medical imaging: Largest dimension of over 11 cm, [27] [28] or craniocaudal height ...
CT angiography is a contrast CT taken at the location and corresponding phase of the blood vessels of interest, in order to detect vascular diseases. For example, an abdominal aortic angiography is taken in the arterial phase in the abdominal level, and is useful to detect for example aortic dissection. [10]
CT image showing mesenteric ischemia with pneumatosis intestinalis and gas in mesenterial and liver veins. Computed tomography (CT scan) is often used. [29] [30] The accuracy of the CT scan depends on whether a small bowel obstruction (SBO) is present. [31] SBO absent. prevalence of intestinal ischemia 23%; sensitivity 64%; specificity 92%
Barium sulfate suspension, often simply called barium, is a contrast agent used during X-rays. [1] Specifically it is used to improve visualization of the gastrointestinal tract (esophagus, stomach, intestines) on plain X-ray or computed tomography. [2] It is taken by mouth or used rectally. [3]
