Objective: This study reports the performance of magnetic resonance imaging (MRI) for diagnosing adnexal torsion in pediatric patients.
Materials And Methods: In this single-center retrospective study, the electronic medical record was queried from 1/1/2015-12/31/2022 for MRI reports of patients 0-18 years old presenting with acute undifferentiated abdominopelvic pain. At our institution, these patients routinely undergo first-line ultrasound (US) for assessment of appendicitis and other relevant differential diagnoses, while indeterminate cases subsequently undergo limited, non-contrast enhanced MRI for further assessment.

Objective: To assess the noninferiority of MRI diagnostic accuracy to CT scan as a second-line examination of acute/subacute abdominopelvic pain in a population of young women after an inconclusive ultrasound (US).
Methods: This prospective, multicenter non-inferiority study included 18-40-year-old non-pregnant women with non-traumatic acute/subacute abdominal pain. They had an inconclusive US warranting the prescription of an additional CT scan.
Background: To evaluate the capability of hyperpolarized [1-C] pyruvate MRI to predict pathologic response to neoadjuvant treatment in multi-site abdominopelvic disease of high-grade serous ovarian cancer (HGSOC) patients and to compare C MRI and [F]-FDG PET/CT measurements for detecting early treatment response. We recruited eight patients with HGSOC in this prospective study who underwent C MRI and [F]-FDG PET/CT before and after the first cycle of neoadjuvant chemotherapy treatment (NACT). Imaging parameters were compared with clinical and histophatologic parameters.

Introduction: The maximum residual tumour size after surgery is the most important prognostic factor related to survival in advanced ovarian cancer. This parameter can be subjectively determined by the surgeon at the end of the operation and by a radiologist with a postoperative CT scan. CT scans after optimal cytoreduction can reveal residual/progressive disease in a significant percentage of patients, ranging from 21% to 49%.

Background: Image-defined risk factors (IDRFs) were introduced to provide a consensus approach for pre-treatment risk stratification on computed tomography (CT) and magnetic resonance imaging (MRI) in patients with neuroblastoma.
Objective: To assess the intra- and inter-reader agreement of radiologists in identifying IDRFs on CT.
Materials And Methods: Approval for this retrospective study was granted by our institutional research ethics board with a waiver of consent.
