Index CT-Based Scoring Systems in Operative Blunt Bowel and Mesenteric Injury Identification.

Introduction: Determining the need for surgical management of blunt bowel and mesenteric injury (BBMI) remains a clinical challenge. The Faget score and Bowel Injury Prediction Score (BIPS) have been suggested to address this issue. Their efficacy in determining the need for surgery was examined.

COVID-view: Diagnosis of COVID-19 using Chest CT.

Significant work has been done towards deep learning (DL) models for automatic lung and lesion segmentation and classification of COVID-19 on chest CT data. However, comprehensive visualization systems focused on supporting the dual visual+DL diagnosis of COVID-19 are non-existent. We present COVID-view, a visualization application specially tailored for radiologists to diagnose COVID-19 from chest CT data.

Pulmonary contusions in the elderly after blunt trauma: incidence and outcomes.

Background: In the general population with blunt chest trauma, pulmonary contusions (PCs) are commonly identified. However, there is limited research in the elderly. We sought to evaluate the incidence and outcomes of PCs in elderly blunt trauma admissions.

Algorithmic approach to utilization of CT scans for detection of internal hernia in the gastric bypass patient.

Background: While surgical exploration remains the gold standard for diagnosing internal hernia (IH) after certain bariatric surgeries, decisions for operative intervention are often based on computed tomography (CT) findings.

Objectives: The aim of this study is to review our institutional experience and create an algorithm to approach patients presenting with abdominal pain and/or emesis after certain bariatric procedures.

Settings: University Hospital

Methods: Following institutional review board approval, a retrospective chart review of all patients presenting with obstruction symptoms after laparoscopic Roux-en-Y gastric bypass (LRYGB) was performed at 2 institutions from 2008 to 2013.

Acute scrotum caused by sigmoid diverticulitis.

Background: Abscesses are one of many complications of diverticulitis and can be found intra-abdominally or in the pelvis.

Methods: Case report and review of the pertinent English-language literature.

Results: We describe an unusual presentation of a diverticular abscess, tracking down the inguinal canal and causing acute scrotum possibly secondary to a hernia.

Staging tools for nonsmall cell lung cancer.

Accurate staging remains the cornerstone of initial managment of nonsmall cell lung cancer. CT offers the potential advantage of identifying early stage tumors when broadly applied as a screening tool, although studies that are evaluating the sensitivity, specificity, and impact on survival are ongoing. PET is a functional imaging tool with ever-broadening applications.

Does pelvic magnetic resonance imaging differentiate among the histologic subtypes of uterine leiomyomata?

Objective: To evaluate if pelvic magnetic resonance imaging (MRI) is reliable for differentiating leiomyoma subtypes.

Design: Prospective study.

Setting: Academic center.

Life-threatening pulmonary hemorrhage with pulmonary arteriovenous malformations and hereditary hemorrhagic telangiectasia.

The occurrence of significant pulmonary hemorrhage associated with pulmonary arteriovenous malformations (PAVMs) and hereditary hemorrhagic telangiectasia (HHT) and the incidence of PAVMs in family members of patients with PAVMs and HHT are poorly defined. We reviewed our experience in 143 patients with PAVMs and HHT. Eleven (8 percent) of the 143 patients with HHT and PAVMs had a history of either massive hemoptysis or of hemothorax which required hospitalization.

Monitoring therapy with a gonadotropin-releasing hormone analog: utility of MR imaging.

The utility of magnetic resonance (MR) imaging in assessing response to therapy with a gonadotropin-releasing hormone (GnRH) analog was assessed in 19 women with uterine leiomyomas and 19 women with endometriosis. There was a significant reduction in individual fibroid volumes at 3 months (P less than .05) and at 6 months (P less than .

Doppler US. Part II. Clinical applications.

Duplex and color Doppler ultrasound (US) are noninvasive techniques capable of providing much information about the condition of blood vessels and flow within them throughout the body. Doppler US provides more than noninvasive angiography. Besides assessment of blood vessel patency and direction of flow, analysis of the flow velocity waveform allows quantitation of arterial stenoses and evaluation of both physiologic and pathologic changes in impedance.

High-field MRI and US evaluation of the pelvis in women with leiomyomas.

Magnetic resonance imaging (MRI) and real-time transabdominal ultrasonography (US) were performed on 23 women with uterine leiomyomas. The uterus, ovaries, and cul de sac were evaluated. Accurate determination of uterine volume was possible in all cases by MRI, but was limited on US in uteri larger than 140 cc.

Endometriosis: appearance and detection at MR imaging.

Thirty-nine magnetic resonance (MR) studies were performed on 31 women with surgically proved endometriosis. A total of 88 endometriotic lesions ranging in size from 0.2 to 7.

Candida epiglottitis in an adult with acute nonlymphocytic leukemia.

A 40-year-old white woman presented with fever, otalgia, and odynophagia and was found to have a peripheral white blood cell count of 90,000/mm3. A diagnosis of acute myelogenous leukemia was made. Further evaluation of symptoms and source for fever led to the diagnosis of Candida albicans epiglottitis.
