Endometrial cancer: correlation of apparent diffusion coefficient with tumor grade, depth of myometrial invasion, and presence of lymph node metastases.
The objective of our study was to investigate whether apparent diffusion coefficient (ADC) values of endometrial cancer differ from those of normal endometrium and myometrium and whether they vary according to histologic tumor grade, the depth of myometrial invasion, or lymph node status. ⋯ ADC values allow normal endometrium to be differentiated from endometrial carcinoma; however, they do not correlate with histologic tumor grade, the depth of myometrial invasion, or whether lymph node metastases are present.

Are chest radiographs routinely indicated after chest tube removal following cardiac surgery?
The purpose of this prospective study was to determine the incidence and clinical significance of pneumothoraces detected on routine radiography after chest tube removal following cardiac surgery and correlate those findings with an immediate postprocedure assessment of the likelihood of new pneumothorax. ⋯ Chest radiography performed after chest tube removal following cardiac surgery is necessary only if the patient has respiratory or hemodynamic changes or if there are problems with the technical aspect of chest tube removal. Following this guideline in our patient population could have eliminated 86.3% of radiographs without missing any clinically significant pneumothoraces.
