INTRODUCTION: Radiology reports, although written primarily for healthcare providers, are read increasingly by patients and their family. This study sought to assess the readability of radiology reports. MATERIALS AND METHODS: From 108,228 consecutive radiology reports from a large US health system, we excluded duplicate reports, reports of research exams, and reports with missing data. For each report, we measured the numbers of words and sentences, and computed a "reading grade level" (RGL) as the mean of three readability indices: Flesch-Kincaid Grade Level, Gunning Fog index, and Simple Measure of Gobbledygook...

INTRODUCTION: Implant performance of cementless THA is often evaluated by radiolucency on plain radiographs, often classified as interference gaps on direct post-operative radiographs. However, the diagnostic performance is unknown. The aim was to evaluate the diagnostic performance of radiographic assessment of post-operative gaps after primary THA by comparing it with CT confirmed gaps, and secondary to define optimal cut-off criteria for assessing gaps on plain radiographs compared with CT...

Digital breast tomosynthesis (DBT) is a new modality that assists in detection of breast cancer. However, benign masses are also detected more easily by DBT and may require further workup. This article reviews typical imaging features of non-calcified benign masses on DBT. We also discuss the management of these benign masses. Knowledge of the imaging features of benign masses on DBT is required to minimize unnecessary callbacks.

We present a 36-year-old man who presented to our emergency department with acute onset shortness of breath and syncope. He was found to have a large left atrial mass on initial computed tomography (CT) which was confirmed by echocardiography. Tumor biopsy and attempted excision were performed, showing a primary cardiac spindle cell sarcoma that was unable to be resected, to which the patient eventually succumbed to. Spindle cell sarcomas of the heart are very rare primary cardiac tumors, with a variable, non-specific presentation...

INTRODUCTION: Childhood pneumonia is a major cause of death in the 3rd world, and undernourishment increases the severity of the condition. We considered axillary thickness as a simple measurement to evaluate nutritional status that can be performed simultaneously with lung ultrasound. Our goal was to determine the distribution of axillary thickness in a cohort of children to determine a threshold for malnutrition. METHODS: Clinical databases were scanned to identify chest computed tomograms (CT) in children between the ages of 0 and 5 years with non-debilitating disease...

Omphalopagus twins are joined ventrally in the umbilical region. In omphalopagus twins, liver's fusion is very frequent, being present in about 80% of cases. Two conjoined twins born in our Hospital were evaluated using plain x-rays, ultrasound (US), gastrointestinal xrays, Tc-99 hepatobiliary scintigraphy (SC) and contrast enhanced computed tomography (CT). There was no bony connection on conventional xrays, neither bowel communication on GI x-rays study. US demonstrated the fusion of left hepatic lobes and a not-quantifiable vascular shunt...

A classic metaphyseal lesion (CML) is highly specific for nonaccidental trauma. Missing CMLs can be devastating to the child as the child can continue to be exposed to inflicted trauma. Yet, there are rare case reports on CMLs that occur due to birth trauma, IV line placement, and treatment for clubfoot. We present a case of a CML in the tibia that occurred in the hospital secondary to physical therapy, that also caused a femoral shaft fracture, in a term child with hypertonic lower extremities secondary to myelomeningocele...
