Radiologic evaluation of the patient with non-small cell lung cancer (NSCLC) includes chest radiographs for detecting nodules, computed tomography (CT) for further characterizing them, CT and magnetic resonance imaging (MRI) to evaluate the mediastinum, and extrathoracic imaging of bones, the adrenal gland, the central nervous system, and liver. The current practice standards for each are revie...

A right aortic arch usually produces several abnormal shadows on a standard frontal film of the chest. The aortic knob protrudes from the right side of the mediastinum, the trachea is deviated to the left, and the descending aorta can be identified along the right side of the spine. A more conclusive diagnosis can be made from the indentation produced by the arch on the barium-filled esophagus....

PURPOSE We evaluated the differences between radiologically measured size and pathologic size of renal tumors. MATERIALS AND METHODS The data from 171 patients who underwent radical or partial nephrectomy for a renal tumor at Ajou University Hospital were reviewed. Radiologic tumor size, which was defined as the largest diameter on a computed tomographic scan, was compared with pathologic tum...

Infarcts of the corpus callosum have not been well documented in the radiologic literature. We present five cases that were unusual in either their clinical or radiologic presentation or both. Biopsies were performed in three of the five cases, and in time, all lesions evolved in a pattern consistent with infarct. Recognition of the varied clinical and radiologic presentation of infarcts of the...

OBJECTIVE We conducted a systematic review of the literature to define the evidence for radiologic dating of fractures in children in the context of child protection. CONCLUSION Radiologic dating of fractures is an inexact science. Most radiologists date fractures on the basis of their personal clinical experience, and the literature provides little consistent data to act as a resource. There...

OBJECTIVE To discuss the clinical, radiologic, and histopathologic characteristics of cervical bronchogenic cysts. DESIGN Retrospective case study using a pathologic database at our institution. SETTING Pediatric hospital. PATIENTS Eight patients with cervical bronchogenic cysts were identified in the past 13 years (January 1994 to December 2007). MAIN OUTCOME MEASURES The patients' cli...

Increased use of radiation therapy and increasing life spans following radiation treatment has led to an increase in the finding of post-radiation central nervous system injury in patients who have previously undergone radiation treatments. At this time, information regarding treatment for patients suffering from this serious side effect is limited and not readily available. It is imperative to...

OBJECTIVE The objective of this article is to provide a practical review of the conditions other than cirrhosis that can result in diffuse surface nodularity of the liver or portal hypertension. CONCLUSION Conditions that can mimic cirrhosis on imaging include pseudocirrhosis of treated breast cancer metastases to the liver, fulminant hepatic failure, miliary metastases, sarcoidosis, schistos...

PATIENTS with hypertension may exhibit clinical signs and biochemical abnorm,alities which point to an adrenal lesion as the underlying cause. The presence of episodic hypertension, Cushing's syndrome, elevated urine vanillylmandelic acid and metanephrine, or persistent hypokalemia is an important finding that suggests an adrenal lesion. Ultimately, the actual demonstration of the lesion, local...
