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.

Abnormal preprocedural international normalized ratio and platelet counts are not associated with increased bleeding complications after ultrasound-guided thoracentesis.
The objective of our study was to identify differences in hemorrhagic complications after ultrasound-guided thoracentesis on the basis of patient coagulation parameters. ⋯ The risk of bleeding after ultrasound-guided thoracentesis performed by radiologists is low even if the preprocedural INR and platelet count are abnormal. An approach in which no coagulation testing or correction is performed before thoracentesis may be justified.
