PHO/CON TM Multi-plane Imager System (PHO/CON) produced 12 pictures from one scan and each picture was sharply focused on a different plane in the subject. The PHO/CON had two detectors, upper and lower. Six anterior and 6 posterior tomographic planes, equally spaced, were obtained at one scanning. The distance between two adjacent tomographic planes was dependent on the collimator and on the setting of the tomographic separation switch. The PHO/CON was used for various urogenital diseases and its clinical value was evaluated. Renal tomoscintigraphs with <99m>^Tc-DMS (dimercaptosuccinate) and skeletal tomoscintigraphs with <99m>^Tc-pyrophosphate or diphosphonate were studied in 60 patients and in 52 patients, respectively. And tomoscintigraphy with <67>^Ga-citrate were performed in several cases, Tomoscintigraphs of a variety of diseases were presented. The lesion of renal parenchyma was visualized more clearly by PHO/CON than by a conventional scinticamera. Especially in peripheral parenchyma the tomoscintigraph gave accurate information for diagnosis. When compared to the conventional scinticamera, the PHO/CON provided additional useful information in 18 of 37 (48.6%) cases with urological renal diseases, but did not provide additional information in the remaining 23 cases with microscopic hematuria or proteinuria. In skeletal and other scanning, the PHO/CON did not fail to detect any lesion visualized with other instruments, and provided additional information and superior resolution without overlap of activity.
