Percutaneous screw fixation of acetabular roof fractures by radiologists under CT and fluoroscopy guidance.
The aim of this study was to evaluate CT- and fluoroscopy-guided percutaneous screw fixation by radiologists in the management of acetabular roof fractures. ⋯ The results of our study showed that nondisplaced acetabular roof fractures could be successfully treated by a minimally invasive technique with an excellent long-term outcome.

Relationship between imaging biomarkers of stage I cervical cancer and poor-prognosis histologic features: quantitative histogram analysis of diffusion-weighted MR images.
The purpose of this study was to determine whether histogram analysis of apparent diffusion coefficient (ADC) values from diffusion-weighted MRI can be used to differentiate cervical tumors according to their histologic characteristics. ⋯ Median ADC is lower in poorly compared with well or moderately differentiated tumors, while lower histogram-positive skew in adenocarcinoma compared with squamous cell carcinoma is likely to reflect the glandular content of adenocarcinoma.

ReviewBreast imaging of the pregnant and lactating patient: imaging modalities and pregnancy-associated breast cancer.
The purpose of this article is to review key clinical, histologic, and imaging features of pregnancy-associated breast cancer. A discussion of imaging modalities, including mammography, ultrasound, and MRI, and imaging-based interventions available for evaluating this population is provided. ⋯ Successful detection of pregnancy-associated breast cancer requires knowledge of key clinical and imaging features of pregnancy-associated breast carcinoma and selection of the appropriate imaging workup and intervention.

Preoperative breast MRI can reduce the rate of tumor-positive resection margins and reoperations in patients undergoing breast-conserving surgery.
In breast cancer patients eligible for breast-conserving surgery, we evaluated whether the information provided by preoperative MRI of the breast would result in fewer tumor-positive resection margins and fewer reoperations. ⋯ Preoperative breast MRI can substantially decrease the rate of tumor-positive resection margins and reoperations in breast cancer patients eligible for breast-conserving surgery.
