Abstract

To address the issue of whether single-photon emission computed tomography (SPECT) may add useful topographic information to neurologic examination in clinical practice, we compared technetium-99m hexamethyl propyleneamine oxime (HMPAO) SPECT and brain CT in 100 consecutive stroke patients involving the following clinical vascular territories: cortical middle cerebral artery (CMCA), 52; deep, 39; anterior cerebral artery(ACA), 3; posterior cerebral artery (PCA), 7. SPECT and CT sensitivity were calculated as the percentage of patients with respectively focal hypoperfusion or hypodensity related to the index event. The overall sensitivity of SPECT was not significantly different from CT (69 vs. 73%). The sensitivity of SPECT was not significantly dependent on the time of investigation (72% within 24 h, 50% on day 2, and 71% after day 3). Compared with CT, the sensitivity of SPECT was statistically significantly higher in CMCA infarcts (89 vs. 71%; p = 0.027) and lower in deep infarcts (40 vs. 69%; p = 0.024). The degree of hypoperfusion was significantly higher in cortical lesions than in deep lesions (27 vs. 9%; p < 0.001). Crossed cerebellar diaschisis seemed less frequent in patients with clinical lesion in the ACA and PCA territory (respectively 30 and 40%) and was not significantly different when the ischemic lesion involved the CMCA (56%) or deep territories (50%). No significant difference was found when SPECT took place within or after 48 h. Thus, the selective SPECT sensitivity according to the site of lesion and the degree of hypoperfusion may help to determine stroke subtypes in the acute phase. In contrast, in the subacute phase, SPECT is as sensitive as CT in mapping the ischemic lesion and should not be recommended for this purpose.

Abstract

Background: Attenuation correction is generally used to PET images to achieve count rate values independent from tissue densities. The goal of this study was to provide a qualitative comparison of attenuation corrected PET images produced by a PET-CT device (CT, 120 kV, 40 mAs, FOV 600 mm) with and without segmentation of transmission data (ACseg+ and ACseg-respectively). Methods: The reconstructed images were compared to attenuation corrected images obtained with a high-energy transmission source (Cs-137 – 662 keV). Thirty oncologic patients were studied using CT and 137Cs for attenuation correction. All image data were acquired using the Gemini PET-CT scanner (Philips Medical Systems). It is an open PET-CT system that consists of the MX8000 multislice CT and the Allegro PET scanner arranged in a separable configuration. Images with ACseg+ and ACseg- were analyzed simultaneously in coronal, sagittal and transaxial planes. Two nuclear medicine physicians reviewed the image sets. Results: The image quality in the area of metal implants was better with ACseg+ than ACseg-, without metal induced artifacts generally observed in CT corrected images. Further the images with ACseg+ were qualitatively comparable to those obtained with 137Cs attenuation correction. Conclusions: In case of metal implants, PET studies corrected by CT should preferably use the ACseg+ method to avoid the image artifacts.
