Prenatal hydrocolpos: imaging findings and differential diagnosis.

Prenatal hydrocolpos is characterized by fluid distension of the vagina. Hydrocolpos can be caused by multiple underlying etiologies and often demonstrates overlapping imaging features compared to other cystic abdominal and pelvic lesions. The purpose of the current pictorial essay is to provide a systematic prenatal magnetic resonance imaging (MRI) approach to differentiating the primary etiologies leading to hydrocolpos. After discussing the fundamental embryological processes involved in vaginal development, the current essay discusses the most common causes of hydrocolpos with their associated prenatal and postnatal imaging features. An approach to distinguishing the more common differential diagnoses is provided. Given the implications of parental counseling and postnatal management, this essay provides an important approach for narrowing differential diagnoses based on prenatal imaging.

Radiology Resident Ownership Scale (RROS): Adapting a Validated Measure of Patient Care Ownership to the Radiology Context.

RATIONALE AND OBJECTIVES: The aim of this study was to develop a validated instrument to measure radiology residents' sense of psychological ownership of patient care. MATERIALS AND METHODS: A previously validated measure of patient care ownership was adapted through a two-step process of expert review and revision by six academic radiology faculty. An online, anonymous survey was distributed to 64 residents and fellows at the end of three consecutive four-week long rotations. We calculated Cronbach's α to determine the scale's internal consistency, performed exploratory factor analysis to identify possible subscales, and conducted bivariate and correlational analysis to establish construct validity. RESULTS: The 11-item ownership scale demonstrated good internal consistency (Cronbach's α = 0.93), and three subscales were identified corresponding to assertiveness, conscientiousness, and confidence/perceived competence. Sense of ownership was significantly associated with training level, prior experience in the type of rotation, stress, sleep, burnout, peer support, relationships with clinical staff, and recognition by department. We found no significant association between ownership and age, gender, type of rotation, site of rotation, type of residency, perceived interruption frequency, or remote work frequency. CONCLUSION: The radiology resident patient care ownership scale demonstrates good internal consistency and preliminary evidence of validity. After further validation, we expect the scale to be a valuable tool in evaluating interventions aimed at increasing radiology residents' sense of ownership.
