RESUMO
Unlike many other subspecialties in radiology, breast radiologists practice in a patient-facing and interdisciplinary environment where team building, communication, and leadership skills are critical. Although breast radiologists can improve these skills over time, strong mentorship can accelerate this process, leading to a more successful and satisfying career. In addition to providing advice, insight, feedback, and encouragement to mentees, mentors help advance the field of breast radiology by contributing to the development of the next generation of leaders. During the mentorship process, mentors continue to hone their listening, problem-solving, and networking skills, which in turn creates a more supportive and nurturing work environment for the entire breast care team. This article reviews important mentorship skills that are essential for all breast radiologists. Although some of the principles apply to all mentoring relationships, ensuring that every breast radiologist has the skills to be both an effective mentor and mentee is key to the future of the profession.

OBJECTIVE: To review breast imaging utilization and epidemiology of breast diseases in male patients referred to our breast center. MATERIAL AND METHODS: A retrospective analysis of all male patients who underwent breast imaging at our institution over a 10 year period (03/14/2008 to 03/13/2018) was performed. Patient history, imaging findings, biopsy reports, surgical interventions and follow-up data were reviewed. RESULTS: Over the 10 year period, 143 male patients (0.1% of referred breast center patients) underwent breast imaging (versus 139,134 female patients). Mean age was 57.4 years (SD 19.7, median 59, range 21-92 years). The most common indication for referral was a palpable breast mass (98%). The most common diagnosis was gynecomastia (72%). Of the 20 (14%) patients who underwent core biopsy; 1 (0.7%) had breast cancer and the remaining 19 had benign pathologies. Follow-up imaging was recommended for 22 (15.4%) patients, of whom 15 (68%) were lost to follow-up. Two patients under the age of 25 years inadvertently underwent initial mammography instead of ultrasound. CONCLUSION: The epidemiology of breast diseases in our male patient population mirrors that of the general male population worldwide; with an overwhelming 99.3% cases falling into benign category. Two-thirds of our male patients for whom short interval follow up was recommended were lost to follow-up, signifying the need for a more proactive approach in ensuring their compliance. It is important to increase awareness among referring clinicians and general radiologists regarding male breast imaging recommendations so that the appropriate imaging study is performed.

BACKGROUND: Normative data for central airway dimensions are a prerequisite to objectively assess large airway pathologies. Studies with computed tomography (CT) measurements of normal trachea and bronchi size in children are scarce. OBJECTIVE: The purpose of this study is to establish normal values of central airway dimensions in children by CT. METHODS: The study included chest CT studies from children aged 0-18 years. Any condition that predisposed the patient to have an abnormal tracheal or bronchial size was excluded. Airway diameters and cross-sectional area (CSA) were measured using double oblique reconstructions at five levels: proximal trachea, mid-trachea, distal trachea, right main bronchus, and left main bronchus. RESULTS: The inclusion criteria were met by 110 subjects (mean age, 10.8 years; SD, 5.2 years). Various regression models that considered the relationship between patient demographics and anteroposterior (AP) diameter, transverse diameter, and CSA at each of the five levels were assessed. R2 was utilized to select the best model. Multiple formulae (using patient age) were developed to calculate expected normal dimensions for five levels in the central airways on the natural log scale. Finally, z-scores were obtained for central airway dimensions at these five levels. CONCLUSION: Normative data in pediatric central airways are crucial to identify large airway pathologies. We propose using the formulae devised in our study to calculate the predicted dimensions of central airways and their z-scores in pediatric patients. Normative data from our study will aid in objective quantification of central airways, increase clinician confidence, and provide appropriate patient care.

PURPOSE: Pelvic organ prolapse (POP) is assessed differently by gynecologists and radiologists. It is clinically staged by physical examination using the POP-Q (Pelvic Organ Prolapse Quantification) system and radiologically staged by modalities such as by Magnetic Resonance Defecography (MRD). The purpose of this study was to correlate the two methods of staging pelvic organ prolapse for each pelvic compartment by comparing correlative anatomic points and differences in technique. This understanding will help synthesize information from two different perspectives and bridge the gap between multiple specialists who participate in the care of patients with complex pelvic floor disorders. METHODS: A retrospective single institution study comparison of patients who underwent both dynamic magnetic resonance pelvic floor imaging and pelvic organ prolapse quantification (POP-Q) at our medical center was done. Two urogynecologists performed the POP-Q and one fellowship-trained radiologist interpreted the MRD and both staged pelvic organ prolapse independently. RESULTS: A total of 280 patients underwent magnetic resonance imaging (MRI) of the pelvic floor from 1/2013 to 12/2017, of whom 68 met our inclusion criteria. When compared to POP-Q, MRI has strong, moderate, and weak correlation for quantification of anterior, middle, and posterior compartment prolapse, respectively. POP-Q measurements Aa, Ba, C, and D are analogous to true pelvic anatomical landmarks which are directly and consistently measurable by MRI, hence accounting for the better correlation in anterior and middle compartments when compared to measurements Ap and Bp which do not correlate with true anatomical landmarks, and hence can explain the weak correlation for posterior compartment prolapse. CONCLUSION: When comparing POP-Q to MRI, anterior and middle compartment prolapse have better correlation than posterior compartment prolapse. Inherent differences that exist in technique and anatomic landmarks used for staging pelvic organ prolapse by clinical exam and imaging criteria account for this. MRD, however, still provides anatomic details on static images, real time simultaneous overview of multi-compartmental prolapse, characterizes contents of cul-de-sac hernias and rectal evacuation on dynamic imaging. Corroborative information derived from both methods of staging organ will result in optimum patient care.

The menisci play an important role in knee kinematics. Their unique anatomy allows them to channel forces generated during knee movements through the larger tibio-femoral condylar surfaces while simultaneously resisting deleterious hoop stresses. Although physiologic meniscal extrusion occurs with every knee joint movement, pathologic meniscal extrusion subjects the knee to persistent and excessive load transmission. This renders the knee structures susceptible to injury or exacerbates worsening of existing knee joint internal derangement. Detection and quantification of meniscus extrusion is important given its association with underlying pathological processes and internal derangements such as cartilage loss, osteoarthritis and meniscal tears. The medial and lateral menisci vary in size, attachments and load transmission, and the medial meniscus is more susceptible to injury. In this article, the authors illustrate the role of meniscus kinematics, and the identification and quantification of medial meniscal extrusion. Multimodality imaging appearances and implications of presence of medial meniscal extrusion in different knee joint pathologies are discussed with review of the relevant literature.

Wandering spleen is a rare clinical entity characterized by splenic hypermobility resulting from laxity or maldevelopment of the suspensory splenic ligaments. The spleen can "wander" or migrate into various positions within the abdomen or pelvis due to this ligamentous laxity. It is usually detected between 20 and 40 years of age, and is more common in women. The clinical presentation of a wandering spleen is variable, it could present as an asymptomatic, incidentally detected, abdominal or pelvic mass, or as an acute abdomen secondary to splenic torsion. Diagnosis in an emergent setting can be challenging as it is a rare cause of acute abdomen and does not produce any symptoms until splenic torsion has occurred. We present and discuss a case of ectopic, torsed spleen resulting in complete infarction of the spleen and severe hepatic vascular compromise, diagnosed by ultrasound, confirmed by computed tomography and effectively managed by splenectomy.

OBJECTIVE: The aim of this study is to evaluate the effect of body mass index (BMI) on peak systolic velocity (PSV) recording in the celiac artery (CA). SUBJECTS & METHODS: Forty male participants were entered prospectively into the study. The subjects were divided into two groups according to their body mass index. Group A included subjects with BMI ≤25 Kg/m(2) and those in group B with BMI >25 Kg/m(2). The diameter and PSV at the origin of CA of subjects in both groups were recorded while the subject positioned in supine and during expiration phase and fasted for 4 hours using duplex ultrasound. Both groups were matched for age and sex. Independent Student's t-test was used to test if there is any statistical significance between diameter and PSV in both groups. RESULTS: Group A's, average age (year, ±SD) was 29.35±1.35 and average BMI (Kg/m(2), ±SD) was 23.1±1.60. Group B's, average age was 30±2.1 and their average BMI was 31±5.1. The average diameter (cm, ±SD) of CA in group A was 0.66±0.076 and in group B was 0.80±0.066. However, the average PSV (cm/s, ±SD) was 117±28.1 in group A and 102±12.4 in group B. Independent student t-test showed statistical significance between both groups for the diameter (p=0.005) and just reached statistical significance for PSV (p=0.049). CONCLUSION: Subjects with higher BMI showed reduced PSV due to a larger CA diameter and probably due to more fatty tissue accumulation around the CA origin.
