OBJECTIVE: Pulmonary Embolism (PE) is an emergency condition that requires immediate treatment. As the symptoms and the risk factors are nonspecific, PE differential diagnosis is often required. Even if angio-CT is considered the gold standard for PE diagnosis, the frequent allergic condition and/or chronic renal failure of patients make, in most cases, not possible the use of contrast enhancement in emergency with even more increasing use of Lung Perfusion Scintigraphy (LPS), as a simple and fast examination with no preparation/contraindication...

Background: Ultrasonography (US) is being recognized as a traditional way of the diagnosis of various thyroid disorders, and this will help in detecting the thyroid tumors in early stage. Thyroid nodules are common and usually benign; steps to diagnose malignancy should include a careful clinical evaluation, laboratory tests, a thyroid US exam and a fine-needle aspiration (FNA) biopsy. Methods: A total of 173 registered cases were used for analysis in this study...

OBJECTIVE: Cervical esophageal stenosis is often diagnosed with a qualitative evaluation of a barium esophagram. Although the esophagram is frequently the initial screening exam for dysphagia, a clear objective standard for stenosis has not been defined. In this study, we measured esophagram diameters in order to establish a quantitative standard for defining cervical esophageal stenosis that requires surgical intervention. STUDY DESIGN: Single institution case-control study...

Background: Parenchymal changes after stereotactic body radiation therapy (SBRT) make differential diagnosis between treatment outcomes and disease recurrence often difficult. The purpose of our study was to identify the radiographic features detectable at computed tomography (CT) scan [high-risk features (HRFs)] that allow enough specificity and sensitivity for early detection of recurrence. Methods: We retrospectively evaluated patients who underwent SBRT for inoperable early stage non-small cell lung cancer (NSCLC)...

Fluorine-18 Fluorodeoxyglucose (18F-FDG) Positron Emission Tomography (PET) hybrid exams (PET/CT, PET/MRI) have become the most common PET imaging tool in the evaluation of the oncologic patient. Therefore, it is of paramount importance that physicians who take care of oncology patients in any capacity, need to be familiar with the basics of when these exams are indicated, how to best prepare the patients, understand the benefits and limitations of the procedure. Additionally, it is important to understand which medical conditions and medications need to be controlled in order to maintain the diagnostic accuracy of these tests...

OBJECTIVE: Emergency Department patients with abdominal pain may require both an ultrasound (US) and computed tomography (CT) for an accurate diagnosis. Patients are often asked to drink oral radiocontrast while awaiting ultrasound, in order to better expedite a CT in the case of a non-diagnostic US. The impact of oral radiocontrast on US image quality has not been studied. We compared the quality of US images obtained before and after the ingestion of oral radiocontrast in healthy adult volunteers...

Salivary gland tumors have a high incidence (90%) within the parotid gland. The acinic cell carcinoma (ACC) represents only 1-3% of the salivary gland tumors, most frequently affecting the parotid. The minor salivary glands rarely develop ACC and when the ACC is localized in these glands, generally, it has a less aggressive evolution. The main criterion in the diagnostic of ACC is the histological examination with the regular Hematoxylin-Eosin (HE) staining and additionally Periodic Acid-Schiff (PAS) special staining...

FilmArray GI Panel (BioFire Diagnostics, Salt Lake City, UT) is a multiplex, on-demand, sample-to-answer, real-time PCR assay for the syndromic diagnosis of infectious gastroenteritis that has become widely adopted and, in some instances, replaced conventional stool culture and parasite exams. Conventional testing has historically been restricted among hospitalized patients due to low diagnostic yield, but it is not known whether use of the FilmArray GI Panel should be circumscribed. Cary-Blair stool samples submitted for FilmArray GI Panel in adult patients admitted to an academic hospital from August 2015 to January 2017 were included in this study...
