“…In addition, domestic studies also observed that the detection rate of the lesion of cortex ingestion defect by planar image was 21.1% while it was 32.9% by SPECT images. And all the cases that planar image determined positive diagnosis were confirmed to have ingestion defect or more lesions of cortex ingestion defect by SPECT images [25]. However, …”

Tc-DMSA planar scan that can analyze the functions of kidney quantitatively provides less information on a lesion than tomography scanning. Therefore, this study applied a high sensitivity all-purpose collimator that is sensitive to photonic signals to 99m Tc-DMSA and carried out a clinical scan with single photon emission computed tomography (SPECT). And diagnostic accuracy and time requirement of were analyzed to know the clinical usefulness of the applied scanning method. 10 subjects were intravenously injected with radiopharmaceutical product (1.0-1.2 MBq/kg) and scanned by a gamma camera with planar scanner (high resolution (HR)-mode, 256×256, 50 kcts/view, 4 image) and SPECT (HR / high sensitive (HS)-mode, 128×128, step and shoot, 180°, variable sec/angle, total 64 frame, OSEM reconstruction), respectively. The collected data was compared with an analysis program. The results showed that HS-mode SPECT detected total counts 1.8-5.6 times more than planar scan. Relative renal function evaluated based on the counts was not significantly different by two scanning methods (p=0.96) and it turned out that test time was shortened by 39% when HS-mode SPECT was used. Therefore, SPECT using HR, HS-mode collimator could analyze renal function more quantitatively than using planar scan and the former could diagnose the location information of a lesion more accurately than the latter as well as shortened test time requirement, which demonstrated the clinical usefulness of 99m Tc-DMSA renal SPECT using high sensitivity all purpose collimator.
