Fluid collections developing after pancreatic transplantation: radiologic evaluation and intervention.

The usefulness of real-time sonography, duplex sonography, computed tomography (CT), cystography, diagnostic aspiration, and percutaneous drainage in the diagnosis and treatment of peri-pancreatic-transplant fluid collections was retrospectively assessed in 46 recipients of extraperitoneal pancreatic transplants. Forty-four abnormalities were identified in the extraperitoneal space at sonography, including four pancreatic pseudocysts associated with malfunction of the pancreatic duct, seven abscesses, six hematomas, nine urinomas, six early postoperative fluid collections that spontaneously resolved, six cases of pancreatitis, and six cases of vascular occlusion. Sonography (including pulsed Doppler sonography) was the procedure of choice in detecting fluid collections and diagnosing pancreatitis, rejection, vascular thrombosis, and pancreatic duct malfunction.

Teleradiology image transmission system: diagnostic accuracy at three matrix sizes for various types of images.

The interpretability of transmitted digitized radiographic images is an important factor in the operation and use of teleradiology systems. Matrix size may influence diagnostic accuracy of the interpretation. Commercially available equipment has certain built-in image enhancement controls that may increase the interpretability of the image received.

X-File: a program for maintaining a radiographic teaching file.

Software designed for entry, retrieval, and maintenance of radiographic case-file data on a microcomputer offers considerable help in maintaining such records in a radiology department. The case files are based on the Index for Roentgen Diagnoses, published by the AmericanCollege of Radiology. The terms and code numbers of the index are included in the software, so that the user need only enter the diagnostic term desired; the code numbers and exact terminology are assigned automatically.

Diagnostic accuracy of a teleradiology image transmission system.

Teleradiology is the remote interpretation of digitized radiographic images by physicians. The images are usually transmitted over telephone lines, but satellite communication has also been used. The interpretability of the transmitted image is an important factor in the operation and use of teleradiology systems.
