Abdominal imaging

A healthy 35-year-old man developed acute pancreatitis a few hours after receiving a 15-minute propofol anesthetic for laser treatment of a urethral stricture (64). He spent 3 weeks in an intensive care unit, requiring both respiratory and renal support. There was no evidence of gallstones on abdominal imaging. There was no defect of lipid metabolism. 

A healthy 21-year-old woman developed acute pancreatitis a day after an anesthetic that lasted 138 minutes, with propofol for induction (66). She recovered after supportive therapy for 6 days. There was no evidence of gallstones on abdominal imaging and there was no defect in lipid metabolism. 

Perflubron (perfluoro-octylbromide) is composed predominantly of carbon and fluorine, and the absence of protons results in a signal void wherever it is found. When it is given entericaUy the bowel is labeled as a signal void on the abdominal image. 

For in vivo RBC labeling, the blood pool scintigraphy should start 10 min after intravenous injection of a bolus of Tc-pertechnetate cardiac dynamic imaging should begin immediately, and abdominal imaging should also begin immediately and at various times up to 24 h. 

Several drugs interfere with the normal biodistribution of Tc-pertechnetate (Hla-dik et al. 1987). Thus, cancer chemotherapeutic agents (methotrexate) can affect brain scintigraphy atropine, isoprenaline, and analgesics interfere in abdominal imaging iodine and other blockers (perchlorate, perrhenate) can modify thyroid uptake.

The introduction of 64-slice MDCT scanners opens a new phase for CT imaging, thanks to the improved spatial resolution on the longitudinal axis as well as the increase speed of acquisition. Since new acquisition protocols make routinely use of suh-millimeter collimation and suh-millimeter image reconstruction, a real volumetric approach to abdominal imaging is made possible.

For abdominal imaging, DECT acquisitions should employ a coUimation of 14 x 1.2 mm rather than 64 X 0.6 mm, as the latter configuration will cause very high image noise on the B detector images. Since a reconstructed slice thickness below 1.2 mm is usually not required for most apphcations in the abdomen, this typically does not represent a significant limitation in terms of spatial resolution. However, the data acquired are not isotropic in the x,y, and z dimensions. 

Off-center positioning of the patient may be beneficial for imaging the kidneys if the site of the lesion is known, for example, a lesion detected on ultrasound. As stated above, the smaller FOV of the B detector can be a limiting factor in abdominal imaging, depending on the body size of the patient. In patients with suspected or...
