CT of kidneys, Ureters and Bladder (CT KUB) is the key investigation in patients with suspected renal colic. It not only provides valuable information related to renal calculi but also excludes its mimics. Since renal calculi are prevalent in a wide age group and often these patients require repeated follow up examinations, it is imperative to decrease the radiation dose in such examinations. This audit and re-audit outline the changes made in acquiring CT data to achieve a goal of low dose in majority of...
Description of activity and work performed
Study (Audit) Design:
Retrospective audit of radiation dose in 50 subjects referred for CT KUB to the department of radiology, SAK, Akureyri was performed over a period of 3 months. All the studies were performed on 128 Slice CT scanner. The study group consisted only of adult patients (pregnant females were excluded).
For each patient, following parameters were recorded:
-Dose Length Product(mGy.cm)
-Scan length (in cms)
-Patient width (in cms).
Effective dose was calculated in mSv for each examination according to European commission formula- Effective...
Conclusion and recommendations
CT being the gold standard for evaluation of renal colic and considering repeated examinations performed for follow up of these patients, radiation dose needs to be optimized. Present audit and reaudit outlines the key changes implemented in our department to optimize the effective dose in these examinations to
