A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists.
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 ...
Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...
Pancreatic cancer is usually staged following a CT scan. [34] The most widely used cancer staging system for pancreatic cancer is the one formulated by the American Joint Committee on Cancer (AJCC) together with the Union for International Cancer Control (UICC).
Yet, CT scan is the best alternative for diagnosing intra-abdominal injury. [1] Computed tomography provides an overall better surgical strategy planning, and possibly fewer unnecessary laparotomies. Abdominal x-ray is therefore not recommended for adults with acute abdominal pain presenting in the emergency department. [2]
A pancreatic pseudocyst is a circumscribed collection of fluid rich in pancreatic ... CT scan. Diagnosis of pancreatic pseudocyst can be based on cyst fluid analysis ...
A pancreatic cyst is a fluid filled sac within the pancreas. They can be benign or malignant. X-ray computed tomography (CT scan) findings of cysts in the pancreas are common, and often are benign. In a study of 2,832 patients without pancreatic disease, 73 patients (2.6%) had cysts in the pancreas. [3] About 85% of these patients had a single ...
A contrast-enhanced CT scan is usually performed more than 48 hours after the onset of pain to evaluate for pancreatic necrosis and extrapancreatic fluid as well as predict the severity of the disease. CT scanning earlier can be falsely reassuring. [33] ERCP or an endoscopic ultrasound can also be used if a biliary cause for pancreatitis is ...
