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 ...
A computed tomography urography (CT urography or CT urogram) is a computed tomography scan that examines the urinary tract after contrast dye is injected into a vein. [1]In a CT urogram, the contrast agent is through a cannula into a vein, allowed to be cleared by the kidneys and excreted through the urinary tract as part of the urine.
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]
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.
An intravenous pyelogram is used to look for problems relating to the urinary tract. [5] These may include blockages or narrowing, such as due to kidney stones, cancer (such as renal cell carcinoma or transitional cell carcinoma), enlarged prostate glands, and anatomical variations, [5] such as a medullary sponge kidney. [6]
Otherwise a noncontrast helical CT scan with 5 millimeters (0.2 in) sections is the diagnostic method to use to detect kidney stones and confirm the diagnosis of kidney stone disease. [ 16 ] [ 57 ] [ 61 ] [ 66 ] [ 7 ] Near all stones are detectable on CT scans with the exception of those composed of certain drug residues in the urine, [ 59 ...

Even though US has a lower sensitivity and specificity than CT for the detection of kidney stones (urolithiasis), US, if available, is recommended as the initial imaging modality in patients with renal colic and suspected urolithiasis. US has no risk of radiation, is reproducible and inexpensive, and the outcome is not significantly different ...
