Subcutaneous abdominal wall masses: radiological reasoning

OBJECTIVE: A 36-year-old woman presented to her primary care physician with right lower abdominal pain. Her physician subsequently requested a CT to rule out appendicitis. Contrast-enhanced CT was performed and revealed no evidence of appendicitis but showed two subcutaneous ovoid soft-tissue masses anterior to the rectus sheath in the upper pelvi ...

Consensus guidelines for periprocedural management of coagulation status and hemostasis risk in percutaneous image-guided interventions

Hematologic management in the patient undergoing percutaneous imageguided intervention is complex because of the wide range of procedures and equally wide range of patient demographics and comorbidities. Concurrent increases in the use of short- and long-term anticoagulation, as well as the increasing use of antiplatelet agents, further complic ...

The revised Atlanta classification of acute pancreatitis: its importance for the radiologist and its effect on treatment

An international working group has modified the Atlanta classification for acute pancreatitis to update the terminology and provide simple functional clinical and morphologic classifications. The modifications (a) address the clinical course and severity of disease, (b) divide acute pancreatitis into interstitial edematous pancreatitis and necrotiz ...

Current role of imaging in the diagnosis and management of pulmonary hypertension

OBJECTIVE: The purpose of this review is to describe classification schemes and imaging findings in the diagnosis and management of pulmonary hypertension. CONCLUSION: Pulmonary hypertension is a complex pathophysiologic condition in which several clinical entities increase pressure in the pulmonary circulation, progressively impairing cardiopul ...

Pulmonary sarcoidosis: typical and atypical manifestations at high-resolution CT with pathologic correlation

Sarcoidosis is a multisystem disorder that is characterized by noncaseous epithelioid cell granulomas, which may affect almost any organ. Thoracic involvement is common and accounts for most of the morbidity and mortality associated with the disease. Thoracic radiologic abnormalities are seen at some stage in approximately 90% of patients with sarc ...

Adrenal imaging

Adrenal nodules are frequently encountered on current high-resolution imaging, and accurate characterization of such lesions is critical for appropriate patient care. Our article highlights how imaging techniques such as CT densitometry, CT washout characteristics, chemical shift MRI, PET, and PET/CT help characterize most adrenal lesions. We focus ...

Temporal Bone Trauma and the Role of Multidetector CT in the Emergency Department

The temporal bone anatomy is complex, with many critical structures in close association with one another. The temporal bone region comprises cranial nerves V, VI, VII, and VIII; vascular structures such as the internal carotid and middle meningeal arteries; sigmoid sinus; jugular bulb; and sensorineural and membranous structures of the inner e ...

Benign biliary strictures: a current comprehensive clinical and imaging review

There is a wide spectrum of nonneoplastic causes of biliary stricture that can pose a significant challenge to clinicians and radiologists. Imaging plays a key role in differentiating benign from malignant strictures, defining the extent, and directing the biopsy. We describe the salient clinical and imaging manifestations of benign biliary strictu ...

Diagnosis of Inguinal Region Hernias with Axial CT: The Lateral Crescent Sign and Other Key Findings

Differentiation of direct inguinal hernias, indirect inguinal hernias, and femoral hernias is often difficult at clinical examination and pre-sents challenges even at diagnostic imaging. With the advent of higher-resolution multidetector computed tomography (CT), the minute anatomic detail of the inguinal region can be better delineated. The author ...
