- Avoiding "pseudo-reversibility" of CT-CBV infarct core lesions in acute stroke patients after thrombolytic therapy: the need for algorithmically "delay-corrected" CT perfusion map postprocessing softwarePamela W Schaefer
Department of Radiology, Division of Neuroradiology, Gray 273A, Massachusetts General Hospital, 55 Fruit Street, Boston, MA 02114, USA
Stroke 40:2875-8. 2009..We sought to determine: (1) the prevalence of CT-CBV "reversibility" in AIS patients treated with thrombolytic therapy, and (2) whether the presumed tissue salvage of these CT-CBV lesions depends on the CTP software...

- CT cerebral blood flow maps optimally correlate with admission diffusion-weighted imaging in acute stroke but thresholds vary by postprocessing platformShahmir Kamalian
Department of Radiology, Massachusetts General Hospital, Gray B285, 55 Fruit Street, Boston, MA 02114, USA
Stroke 42:1923-8. 2011..Our purposes were to: (1) determine the optimal CT perfusion parameter to define infarct core using various postprocessing platforms; and (2) establish the degree of variability in threshold values between these different platforms...

Department of Radiology, Winthrop University Hospital, Mineola, New York 11501, USA
AJNR Am J Neuroradiol 33:370-5. 2012..Nevertheless, patients may continue to have significant back pain afterward. The purpose of this study was to assess the source of persistent or recurrent back pain following vertebral augmentation...
