Comparative StudyGastric cancer: evaluation of triphasic spiral CT and radiologic-pathologic correlation.
The purpose of this study was to evaluate the utility of triphasic spiral CT with water-filling method in the preoperative T staging of gastric cancer. ⋯ Spiral CT with triphasic scan technique improved the accuracy of estimating the depth of tumor invasion in advanced gastric cancer.

Comparative Study Clinical Trial Controlled Clinical TrialImaging articular cartilage defects with 3D fat-suppressed echo planar imaging: comparison with conventional 3D fat-suppressed gradient echo sequence and correlation with histology.
Our goal was to shorten examination time in articular cartilage imaging by use of a recently developed 3D multishot echo planar imaging (EPI) sequence with fat suppression (FS). We performed comparisons with 3D FS GE sequence using histology as the standard of reference. ⋯ The 3D FS EPI sequence is comparable with the 3D FS GE sequence in the noninvasive evaluation of advanced cartilage abnormalities but reduces scan time by a factor of 4.

Bowel and mesenteric injuries are common sequelae of blunt abdominal trauma. CT represents a valuable modality in the diagnosis of bowel and mesenteric injuries. While certain findings on CT are highly specific, such as free air and extravasation of oral contrast agent, they are insensitive and seen only in the minority of patients. ⋯ Mesenteric abnormalities, which can consist of mesenteric infiltration, interloop fluid, or fluid trapped in the leaves of the small bowel mesentery, may be crucial yet subtle clues. Knowledge of their typical appearance may aid in their diagnosis. This pictorial essay illustrates the range of findings in bowel and mesenteric injuries as well as possible pitfalls to help in their prompt recognition and diagnosis.

Blunt bowel and mesenteric injury: diagnostic performance of CT signs.
Our goal was to determine the sensitivity and specificity of various CT signs of blunt bowel and mesenteric injury. ⋯ Bowel wall thickening, bowel wall discontinuity, extraluminal air, and mesenteric hematoma are reasonably specific CT signs of bowel and mesenteric injury following blunt abdominal trauma. The presence of a moderate to large volume of intraperitoneal fluid without visible solid organ injury is an important sign of bowel or mesenteric injury.

Suspected scaphoid fractures in skeletally immature patients: application of MRI.
The purpose of our study was to evaluate the MR findings in the wrists of pediatric patients who have sustained acute wrist injuries and to determine if this imaging method yields more information than combined serial radiographs and physical examinations. ⋯ A normal initial MR image had a negative predictive value of 100%. Persistent snuffbox pain may represent injury to the scaphoid, extensor tendons, or dorsal soft tissues. An outcome study evaluating the benefits of early application of MR in the pediatric population is warranted.
