Safety of repeated radioembolizations in patients with advanced primary and secondary liver tumors and progressive disease after first selective internal radiotherapy.

Unlabelled: The purpose of this study was to assess the safety of repeated (90)Y radioembolization with resin microspheres in patients with extensive primary and secondary liver tumors after failure of first radioembolization.

Methods: Between 2007 and 2011, 21 patients (12 women, 9 men; mean age, 61.0 y) with nonresectable advanced liver tumors (breast cancer liver metastases, n = 7; colorectal liver metastases, n = 5; hepatocellular carcinoma, n = 8; cholangiocellular carcinoma, n = 1) were repeatedly treated by radioembolization.

Estimation of return-to-sports-time for athletes with stress fracture - an approach combining risk level of fracture site with severity based on imaging.

Background: The aim was to compare the return-to-sports-time (RTST) following stress fractures on the basis of site and severity of injury. This retrospective study was set up at a single institution. Diagnosis was confirmed by an interdisciplinary adjudication panel and images were rated in a blinded-read setting.

MRI versus bone scintigraphy. Evaluation for diagnosis and grading of stress injuries.

Aim: This study was set up to determine the value of magnetic resonance imaging (MRI) and bone scintigraphy (BS) for the diagnosis of stress injuries in athletes, and furthermore to assess reliability and prediction of healing time.

Patients, Methods: Imaging data was analyzed retrospectively from 28 athletes who had received MRI and BS examinations for suspected stress injuries. MRI- and BS-data were rated by three specialists each in a blinded read, using a 5-point score (i.

Blinded-read of bone scintigraphy: the impact on diagnosis and healing time for stress injuries with emphasis on the foot.

Aim: This study evaluated the use of bone scintigraphy (BS) for the diagnosis of stress fractures in athletes and its validity for the prediction of healing time, with a focus on foot injuries.

Methods: In our retrospective study, 84 athletes with a total of 93 suspected stress fractures (foot, n = 66; others, n = 27) were included. A blinded-read of BS was performed by 3 observers.

Gene profiling identifies genes specific for well-differentiated epithelial thyroid tumors.

Thyroid nodules are common. It would very helpful if genetic markers that can diagnose malignancy from fine needle aspiration samples were available. Few such markers has been thus identified and none are specific.
