irregular borders ( fig. 2 ). It was histologically diagnosed as a pure nonmucinous bronchioloalveolar carcinoma (BAC) ( fig. 3 ). The patient was alive without signs of tumor recurrence 6 months later. BAC is known for low FDG uptake presumed to be secondary to the lower proliferation rate of these tumors [1] . Particularly low metabolic activity is observed in pure BAC, unifocal and mucin-con...

The diagnosis of ischemic cerebral infarction by CT usually is not possible for 12-24 hr after the event. A sign that allows earlier diagnosis is increased density of a cerebral vessel secondary to a thrombus or embolus. We report 19 cases of increased density in a middle cerebral artery or one of its major branches visible on the initial CT scan of patients subsequently clinically proven to ha...

any portion of the membranous or the bony labyrinth. A primary or secondary deficiency of the cochlear nerve may also present as a congenital anomaly. CT and MRI allow for a detailed analysis of each lesion and they can provide guidance for the proper treatment of each patient. Both CT and MR imaging can be used to detect inner ear malformations, yet the two techniques are often complementary. ...

The primary importance of magnetic resonance (MR) imaging in evaluating anal fistulas lies in its ability to demonstrate hidden areas of sepsis and secondary extensions in patients with fistula in ano. MR imaging is relatively expensive, so there are many healthcare systems worldwide where access to MR imaging remains restricted. Until recently, computed tomography (CT) has played a limited rol...

Repetitive sequences have been proposed to be recombinogenic elements in eukaryotic chromosomes. We tested whether dinucleotide repeats sequences are preferential sites for recombination because of their high affinity for recombination enzymes. We compared the kinetics of the binding of the scRad51, hsRad51 and ecRecA proteins to oligonucleotides with repeats of dinucleotides GT, CA, CT, GA, GC...

A 50-year-old woman developed multiorgan system failure secondary to sepsis. She became obtunded during a period of hypotension, and cranial CT demonstrated diffuse borderzone infarction. Brain autopsy revealed green pigmentation in areas of infarction due to vascular leakage of bilirubin at sites of blood–brain barrier disruption, mapping the borderzone regions and bilateral posterior anterior...

OBJECTIVE To evaluate trends in and factors associated with computed tomography (CT) use among children presenting to the emergency department (ED) with abdominal pain. METHODS This study was a cross-sectional, secondary analysis of the National Hospital Ambulatory Medical Care Survey data from 1998 to 2008. We identified ED patients aged <19 years with abdominal pain and collected patient de...

The use of FDG PET/CT in the assessment of oncologic disease is becoming increasingly widespread. The advent of PET/CT however presents some additional challenges; recent reports have emphasized the need to detect incidental findings which can confer additional health risks. We report a case of a pulmonary embolus with pulmonary infarct secondary to a metastatic right atrial mass on a backgroun...

Chlamydia trachomatis (CT), the most prevalent sexually transmitted infection in the United States, disproportionately infects women and people of color. This study aimed to identify risk factors for racial and ethnic disparities for CT infection, re-infection, and persistent infection among pregnant women. We present a secondary analysis of births from a retrospective cohort study in Syracuse,...

For two patients with partial Budd-Chiari syndrome secondary to hepatocellular carcinoma, dynamic CT was evaluated. The obstructed hepatic veins were both the middle and left hepatic veins in Case 1 and the right hepatic vein in Case 2. The area affected by obstructed hepatic vein(s) was seen as low density on both unenhanced and contrast enhanced CT in Case 1 and as high density on enhanced CT...
