The standard abdominal X-ray protocol is usually a single anteroposterior projection in supine position. [3] Special projections include a PA prone, lateral decubitus, upright AP, and lateral cross-table (with the patient supine).
The standard abdominal X-ray protocol is usually a single anteroposterior projection in supine position. [15] A Kidneys, Ureters, and Bladder projection (KUB) is an anteroposterior abdominal projection that covers the levels of the urinary system, but does not necessarily include the diaphragm.
The average radiation dose from an abdominal X-ray is 0.7 millisieverts (0.0007 Sv), that from an abdominal CT scan is 8 mSv, that from a pelvic CT scan is 6 mGy, and that from a selective CT scan of the abdomen and the pelvis is 14 mGy. [7]
A DEXA scan (dual-energy X-ray absorptiometry) is the “gold standard” for calculating body composition because it’s low cost, low radiation, and very accurate, Dr. Busse says.
The stepladder sign is a radiological finding observed in the context of small bowel obstruction on abdominal X-rays or computed tomography scans. It refers to the appearance of multiple, dilated small bowel loops arranged in a step-like configuration, typically visible in upright or lateral decubitus imaging positions.
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 ...
The falciform ligament sign is a radiological sign observed on abdominal imaging in cases of pneumoperitoneum, where free intraperitoneal air outlines the falciform ligament. [1] This sign is considered a diagnostic indicator of free air within the abdominal cavity and is most commonly identified on computed tomography (CT) scans and less ...
This excreted material will collect in the gallbladder, where reabsorption of water concentrates the excreted contrast. Since only 10% of gallstones are radiopaque, the remaining 90% will appear as translucent on an opaque background in an abdominal X-ray. If needed, intravenous cholecystography and cholangiography may be done. [citation needed]
