Hydrogen-1 MR spectroscopy enables identification of mild to moderate AD with a specificity and sensitivity that suggest clinical utility.

Changes in nADC as measured by diffusion-weighted imaging can predict response to STI.

We report two cases of spontaneous bladder rupture. Preoperative diagnosis was difficult and the correct diagnosis was made at surgery. Reviewing the initial abdominopelvic CT of our second patient, the bladder wall defect and blood attenuation near the bladder were observed. These findings were consistent with the operative findings, and would have led to correct preoperative diagnosis if we had had sufficient knowledge of spontaneous bladder rupture. Under urinary catheterization, ascites and free intraperitoneal air were identified in both patients. These findings were indistinguishable from those for bowel perforation, which was our preoperative diagnosis. Significant changes in ascites volume between pre and post urinary catheterization can be an indication of spontaneous bladder rupture.

The internal mammary artery contributes to the perfusion of lesions responsible for hemoptysis when the basic lesion involves the pulmonary parenchyma adjacent to the anterior pleural surface. Initial distal occlusion of the internal mammary artery may improve the efficacy of embolization of this artery for hemoptysis.

REG Ialpha expression in squamous cell esophageal carcinoma may be a reliable marker of chemoradiosensitivity. We anticipate that it will enable us to provide more appropriate and individualized treatment to patients of advanced esophageal squamous cell carcinoma.
