Recognizing the CT Manifestations of Gynecologic Conditions Encountered in the Emergency Department.

Curr Probl Diagn Radiol 2018 Jul 23. Epub 2018 Jul 23.

Department of Diagnostic Radiology, University of Kentucky Chandler Medical Center, 800 Rose St. HX315E, Lexington, KY.

Women commonly present to the emergency room with subacute or acute symptoms of gynecologic origin. Although a pelvic exam and ultrasound (US) are the preferred initial diagnostic tools for gynecologic entities, a CT is often the first line imaging modality in the emergency department. We will provide a review of normal uterine enhancement and normal pregnancy related findings, and then familiarize radiologists with the CT appearances of gynecologic entities classically described on ultrasound that may present to the emergency department.

Curr Probl Diagn Radiol 2018 Aug 17. Epub 2018 Aug 17.

Einstein Medical Center, Department of Radiology, Philadelphia, PA. Electronic address:

Nonthrombotic pulmonary embolism (NTPE) is less well understood and is encountered less frequently than pulmonary embolism from venous thrombosis. NTPE results from embolization of nonthrombotic material to the pulmonary vasculature originating from many different cell types as well as nonbiologic or foreign materials. For many radiologists NTPE is a challenging diagnosis, presenting nonspecific or unusual imaging findings in the setting of few or unusual clinical signs. Read More

Monitoring the Use of Extra Images on Chest Radiography Examinations.

Curr Probl Diagn Radiol 2018 Jul 29. Epub 2018 Jul 29.

Pennsylvania Hospital, Philadelphia, PA.

Background: A large number of chest radiography studies in our department include extra images due to incompletely imaged anatomy (eg, extra frontal view to include a truncated costophrenic angle). Negative impacts include: increased radiologist review time due to disruption of search pattern and the need to review additional films in slightly different obliquities, additional radiation exposure, and increased technologist time expenditure.

Purpose: To determine the chest radiograph repeat rate, collaborate with technologists on a process to decrease the frequency, and incorporate the process into our quality control program. Read More

Morgagni Hernia Causing Incarcerated Bowel and Contributing to Cardiac Arrest.

Curr Probl Diagn Radiol 2018 Jul 31. Epub 2018 Jul 31.

Department of Radiology, Allegheny Health Network, Pittsburgh, PA.

A Morgagni hernia is a congenital diaphragmatic hernia (CDH)-incomplete formation of the diaphragm. Though congenital diaphragmatic hernias (CDHs) are a common class of birth defect, the majority are diagnosed either prenatally or shortly after birth since these patients can present with cardiopulmonary failure due to pulmonary hypoplasia or pulmonary hypertension. However, the Morgagni type of CDH predisposes it to go undetected well into adulthood. Read More
