TL;DR: The addition of SPECT/CT resulted in a significant reduction of equivocal reports; a definitive diagnosis was given in the majority of the patients due to the improved diagnostic confidence compared to planar or SPECT imaging alone in prostate cancer patients with suspected bone metastases.
Abstract: The purpose of this study was to investigate the additional value of single photon emission computed tomography/computed tomography (SPECT/CT) over whole-body planar bone scintigraphy and SPECT in prostate cancer patients in terms of diagnostic confidence, inter-reviewer agreement and the possible impact on the clinical management. This was a retrospective review of 40 consecutive prostate cancer patients (mean age 71 years) who underwent 99mTc-methylene diphosphonate (MDP) whole-body planar bone scintigraphy, SPECT and SPECT/CT between April 2006 and April 2008. The images were evaluated by two independent reviewers; inter-reviewer agreement was evaluated using a weighted kappa score. Each focus of abnormal increased tracer uptake was recorded using a 4-point diagnostic confidence scale. Institutional Review Board approval was obtained. Fifty lesions on planar bone scintigraphy in the 40 patients were evaluated. On reporting the planar study and SPECT scans, reviewers rated 61% of lesions as equivocal. On reporting the SPECT/CT scans only 8% of lesions were rated as equivocal, 24% were rated as malignant and 68% as benign. Weighted kappa scores for inter-reviewer agreement were 0.43 for bone scintigraphy, 0.56 for SPECT and 0.87 for SPECT/CT. All were significant at p < 0.0001. Follow-up imaging confirmed the SPECT/CT diagnoses in 14 patients. The addition of SPECT/CT resulted in a significant reduction of equivocal reports; a definitive diagnosis was given in the majority of the patients due to the improved diagnostic confidence compared to planar or SPECT imaging alone in prostate cancer patients with suspected bone metastases.

TL;DR: In vivo imaging of activated microglia/brain macrophages provides a dynamic measure of active tissue changes following an acute focal lesion, demonstrating that the glial tissue response in the wake of neuronal damage is protracted and widespread within the confines of the affected distributed neural system and can be related to the long-term functional deficits.
Abstract: A major challenge in the assessment of brain injury and its relationship to the ensuing functional deficits is the accurate delineation of the areas of damage. Here, we test the hypothesis that the anatomical distribution pattern of activated microglia, a normally dormant population of resident brain macrophages, can be used as a surrogate marker of neuronal injury not only at the primary lesion site but also in the antero- and retrograde projection areas of the lesioned neurones. Two patients with asymmetrical herpes simplex encephalitis were serially scanned 6 and 12 months after the acute illness using PET with [11C] (R)-PK11195, a marker of activated microglia/brain macrophages. The evolving structural changes in the brain were measured by volumetric MRI and compared with the pattern of [11C](R)-PK11195 binding. Corresponding to the clinically observed cognitive deficits, quantitative [11C](R)-PK11195-PET revealed highly significant signal increases within the affected limbic system and additionally in areas connected to the limbic system by neural pathways, including the lingual gyrus in the occipital lobe and the inferior parietal lobe, which had normal morphology on structural MRI. The increased [11C](R)-PK11195 binding, signifying the presence of activated microglia, persisted many months (>12) after antiviral treatment. Cortical areas that showed early high [11C](R)-PK11195 binding subsequently underwent atrophy. These observations demonstrate that in vivo imaging of activated microglia/brain macrophages provides a dynamic measure of active tissue changes following an acute focal lesion. Importantly, the glial tissue response in the wake of neuronal damage is protracted and widespread within the confines of the affected distributed neural system and can be related to the long-term functional deficits.
