Pulmonary arterial perfusion was evaluated by perfusion lung scans in ten dogs experimentally infected with heartworm. After larval inoculation, scans were done once a month for 11 months. In 8 of 10 dogs, pulmonary arterial perfusion deficits were detected. The perfusion deficits involved the left cranial, right cranial, and right caudal lung lobes. Generally, there was a poor correlation between vascular abnormalities detected on the survey thoracic radiographs and the perfusion deficits detected by lung scanning. The perfusion deficits did not produce clinical signs or pulmonary infarction.
通过灌注肺扫描评估了10只实验感染心丝虫的犬的肺动脉灌注情况。幼虫接种后，连续11个月每月进行一次扫描。10只犬中有8只检测到肺动脉灌注缺损。灌注缺损累及左颅叶、右颅叶和右尾叶。一般来说，胸部X线检查发现的血管异常与肺扫描检测到的灌注缺损之间相关性较差。灌注缺损未产生临床症状或肺梗死。
