Results: First audit: 60% cases were females and 40% were males. 38 cases were of age 41-60 years. In 12% cases, the enhancement of pulmonary trunk was below 211 HU thus unsatisfactory scans. This showed 5% deviation from the standard. In 15 cases, there is acute pulmonary embolism.

Second audit: 58% cases were females and 42% were males. In 3% cases, the enhancement of pulmonary trunk was below 211 HU thus unsatisfactory scans. For set standard, the target was achieved. In 22% cases, there is acute pulmonary embolism.
