ACR Manual on Contrast Media

This manual was developed by the ACR Committee on Drugs and Contrast Media of the ACR Commission on Quality and Safety as a guide for radiologists to enhance the safe and effective use of contrast media. The Committee offers this document to practicing radiologists as a consensus of scientific evidence and clinical experience concerning the use ...

Anatomy and pathology of the facial nerve

The facial nerve (cranial nerve [CN] VII) is a frequently overlooked structure on imaging examinations. Knowledge of the normal anatomy, embryology, and spectrum of abnormality will aid radiologists in correctly diagnosing lesions of the facial nerve. In this article, we review normal facial nerve anatomy, clinical presentations, imaging approaches ...

Adult Abdominal Hernias

1. Given that abdominal hernias are a frequent imaging finding, radiologists not only are required to interpret the appearances of abdominal hernias but also should be comfortable with identifying associated complications and postrepair findings. 2. CT is the imaging modality of choice for the assessment of a known adult abdominal hernia in both e ...

Gallbladder wall thickening

Gallbladder wall thickening is a common yet nonspecific finding that can occur in a wide range of gallbladder diseases and extracholecystic conditions. Distinguishing among the wide variety of conditions associated with gallbladder wall thickening is important for diagnosis and directing appropriate management. An initial critical diagnostic observ ...

Adult bile duct strictures: role of MR imaging and MR cholangiopancreatography in characterization

Bile duct strictures in adults are secondary to a wide spectrum of benign and malignant pathologic conditions. Benign causes of bile duct strictures include iatrogenic causes, acute or chronic pancreatitis, choledocholithiasis, primary sclerosing cholangitis, IgG4-related sclerosing cholangitis, liver transplantation, recurrent pyogenic cholangitis ...

Brain PET in suspected dementia: patterns of altered FDG metabolism

The diagnosis of dementia syndromes can be challenging for clinicians, particularly in the early stages of disease. Patients with higher education levels may experience a marked decline in cognitive function before their dementia is detectable with routine testing methods. In addition, comorbid conditions (eg, depression) and the use of certain med ...

Detection of lung cancer through low-dose CT screening (NELSON): a prespecified analysis of screening test performance and interval cancers

Summary Background Low-dose CT screening is recommended for individuals at high risk of developing lung cancer. However, CT screening does not detect all lung cancers: some might be missed at screening, and others can develop in the interval between screens. The NELSON trial is a randomised trial to assess the effect of screening with increasing ...

Expiratory Air Trapping on Thoracic Computed Tomography A Diagnostic Subclassification

Abstract Rationale: Multiple causes for air trapping as identified by expiratory computed tomography (CT) have been reported, but a unified evaluation schema has never been proposed. Objectives: It was our purpose to identify imaging features that would help distinguish etiologies of mosaic air trapping. Methods: Cases with the term “air trap ...

Traumatic elbow injuries: what the orthopedic surgeon wants to know

Traumatic elbow injuries are commonly encountered in the emergency department setting, but their complexity and clinical significance often go unrecognized at the initial evaluation. Initial imaging in patients with elbow trauma should not only help identify major injuries that require immediate intervention but also allow detection of other, often ...

Classification of acute pancreatitis--2012: revision of the Atlanta classification and definitions by international consensus

BACKGROUND AND OBJECTIVE: The Atlanta classification of acute pancreatitis enabled standardised reporting of research and aided communication between clinicians. Deficiencies identified and improved understanding of the disease make a revision necessary. METHODS: A web-based consultation was undertaken in 2007 to ensure wide participation of pan ...
