Diagnosing Acute Pyelonephritis with CT, 99mTc-DMSA SPECT, and Doppler Ultrasound: A Comparative Study

Purpose With growing interest in early imaging, the aim of our study was to define the most practical modality for routine clinical use for the diagnosis of acute pyelonephritis (APN). We compared the sensitivity of enhanced computerized tomography (CT), dimercaptosuccinic acid (DMSA) scintigraphy, and Doppler ultrasonography (DUS) by using clinical findings as the standard of reference.
