Hyperalimented Lung Diagnosed by Perfusion Scan

Clinical Nuclear Medicine, 1984
Injection of radiopharmaceutical through a catheter may be useful in localizing its placement. A case is described in which a central venous line had punctured to superior vena cava, delivering hyperalimentation solution into the right pleural space.

Perfusion Lung Scan in Lymphangitic Carcinomatosis

Clinical Nuclear Medicine, 2001
The authors describe the findings of perfusion lung scintigraphy in a case of lymphangitic carcinomatosis in a 30-year-old man with recent symptoms of progressive dyspnea, hypoxemia, and thoracic pain. The diagnosis of lymphangitic carcinomatosis was made by transbronchial lung biopsy. The primary tumor was a gastric adenocarcinoma.

Ventilation and perfusion scanning in children

Paediatric Respiratory Reviews, 2000
Ventilation and perfusion scintigraphy (VQ scans) provide a relatively non-invasive evaluation of lung function. They indicate the relative blood flow to each lung and allow a quantitative assessment of the perfusion of each lung segment. They can detect areas of abnormal aeration and demonstrate air trapping. However, VQ scanning gives relatively poor

Fractal Texture Analysis of Perfusion Lung Scans

Computers and Biomedical Research, 2000
The purpose of this study is to investigate if fractal texture analysis can assist in the diagnostic interpretation of perfusion lung scans. Forty-five perfusion scans were acquired from patients with clinical suspicion of acute pulmonary embolism (PE) who underwent pulmonary angiography for final diagnosis.

CHAPTER VIII: Perfusion Lung Scanning

Circulation, 1973
Lung scans at 24 hours after the onset of infusion indicated that restoration of pulmonary arterial blood flow was more rapid in patients who received a 12-hour urokinase infusion than in patients treated with heparin alone. Patients with recent emboli (less than 48 hours old) appeared to respond better to urokinase than patients with older emboli (48 ...

Xenon Ventilation-Perfusion Lung Scans

JAMA, 1978
The use of xenon Xe 133 ventilation-perfusion lung scans for the early diagnosis of inhalation injury was evaluated in 67 patients with acute thermal burns. Study results were interpreted as normal if there was complete pulmonary clearance of the radioactive gas by 150 seconds. Thirty-two scans were normal, 32 abnormal, and three technically inadequate.

Missed Pneumothorax Seen on Ventilation–Perfusion Scan

Clinical Nuclear Medicine, 2002
A 38-year-old woman came to the emergency department with acute onset of shortness of breath and pleuritic chest pain. She reported having been on a 4-hour car trip the day before and her medical history was significant for oral contraceptive use. An upright chest radiograph taken in the emergency department was interpreted by the clinician as normal ...
