Invasive pulmonary aspergillosis (IPA) in immunocompromised patients is often difficult to diagnose. Many pathogens present initially with similar, nonspecific pulmonary findings. Air crescent formation has been reported to be highly suggestive of IPA in the appropriate clinical setting, but this is a late sign in an otherwise rapidly fatal infection. The(More)
Computed tomographic (CT) scans of the chest in 39 patients with Pneumocystis carinii pneumonia (PCP) were reviewed to determine the spectrum and frequency of CT manifestations of PCP. Parenchymal disease was categorized as either bilateral or unilateral, symmetric or asymmetric, and diffuse or patchy. Infiltrates were classified as interstitial, airspace,(More)
Over 80 percent of patients with invasive pulmonary aspergillosis (IPA) undergoing intensive antileukemic chemotherapy in a recent two-year period survived the pulmonary infection as a result of early diagnosis and aggressive therapy with high-dose amphotericin B and 5-fluorocytosine. CT played an important role in establishing the early diagnosis of IPA(More)
Computed tomography (CT) is the study of choice for the detection and staging of Hodgkin and non-Hodgkin lymphoma. CT enables accurate measurement of both tumor extent and volume and provides information that can be used to plan an appropriate therapeutic regimen as well as follow patient response to therapy. This article presents a systematic review of the(More)
PURPOSE To compare spiral computed tomography (CT) with interscan spacing of 4-5 mm versus 8-10 mm for detection rate and level of confidence in diagnosis of pulmonary nodules. MATERIALS AND METHODS Four radiologists (two junior and two senior faculty members) retrospectively reviewed 67 spiral CT studies with one to six nodules per study. Every second(More)
PURPOSE To determine the safety and feasibility of percutaneous cryoablation with computed tomographic (CT) guidance in a pig liver model. MATERIALS AND METHODS Nine angiographic balloons (mean diameter, 9 mm) were placed in the livers of seven domestic pigs (mean weight, 30.0 kg +/- 14.0 [SD]) as tumor-mimicking lesions. By using ultrasonographic and CT(More)
During a 2-year period, 15 of 110 patients (14%) admitted for intensive therapy of acute leukemia associated with prolonged deep granulocytopenia developed documented invasive aspergillosis (IA). Antemortem diagnosis was accomplished in 14, and 13 of 15 (87%) survived the infection. Because of the high success rate, we reviewed the courses of the 15(More)
