Pelvic magnetic resonance (MR) imaging is limited by lack of an effective bowel contrast agent. This study was performed to evaluate the efficacy of rectally administered barium sulfate as a contrast agent in pelvic MR imaging. Thirty-two patients were studied retrospectively to evaluate anatomic definition of the rectosigmoid colon. A commercially available barium sulfate suspension was administered rectally in 19 patients. Thirteen patients were imaged without barium. In the latter patients, anatomic definition of the rectum and sigmoid colon was poor to fair with all pulse sequences. Delineation of the rectum and sigmoid colon improved in patients who received rectal barium, owing to distention and marking of the bowel by the predominantly low-signal-intensity barium. Barium is a safe, inexpensive negative contrast agent for bowel that may improve pelvic MR imaging.

Are we underestimating pathological fracture risk in malignant bone lesions of the proximal humerus?
Skeletal Radiol
January 2025
Department of Trauma, Hand and Reconstructive Surgery, University Hospital Jena, Am Klinikum 1, 07747, Jena, Germany.
Objective: This study is aimed at evaluating the distribution of metastatic bone disease (MBD), with a particular focus on the humerus, and its association with pathological fractures. Factors for contributing to the underestimation of fracture risk were assessed, including their impact on surgical management.
Materials And Methods: We retrospectively reviewed patient records of patients undergoing surgical treatment for MBD at our institution between 2005 and 2023.
The response to pericapsular soft tissue and pelvic realignment therapy may be partially predicted by the relevant factors influencing the program's response of the candidates with hip osteoarthritis for joint replacement.

Objective: To explore the risk factors for discontinuation of pericapsular soft tissue and pelvic realignment (PSTP-R) therapy derived from Shiatsu in the candidates with osteoarthritis for total hip replacement (THR) (i.e., candidates for total hip replacement) treated from 2017 to 2020, and to identify the effect modifiers of PSTP-R therapy for patients who continued therapy for 6 months.

Background: pelvis and shoulder are deeply integrated. They are connected by myofascial slings. The pelvic and spinal posture affects the position of the scapula and the activity of its muscles and affects acromio-humeral distance and so that affects shoulder movement.

Objectives: To investigate the impact of compressed sensing - sensitivity encoding (CS-SENSE) acceleration factor on the diagnostic performance of magnetic resonance imaging (MRI) within standard female pelvis protocol in patients with endometrial cancer.
Methods: T2-weighted turbo spin echo (TSE) sequence from standard female pelvic MRI protocol was chosen due to its long acquisition time and essential role in the evaluation of morphological characteristics of the female pelvic anatomical structures. Fully sampled reference scans and multiple prospectively 2x to 5x under-sampled CS-SENSE scans were acquired.
Extra-adrenal Pheochromocytoma of the Urinary Bladder in an Adolescent Female Patient.

Pediatric Radiology, Detroit Medical Center, Wayne State University, Detroit, USA.
Pheochromocytoma is a catecholamine-secreting tumor that arises from the medullary chromaffin cells but can rarely be extra-adrenal in origin. We present a case of a 16-year-old female patient with uncontrolled hypertension, despite being on lisinopril and metoprolol, and associated left-sided chest pain, recurrent headaches, and an unintentional weight loss of 10 pounds in one month. Laboratory work-up showed a markedly elevated plasma metanephrine level of 4463.
