Quantitative simultaneous Tc/ I cardiac SPECT using MC-JOSEM
Simultaneous rest Tc-Sestamibi / I-BMIPP cardiac SPECT imaging has the potential to replace current clinical Tc-Sestamibi rest/stress imaging and therefore has great potential in the case of patients with chest pain presenting to the emergency department. Separation of images of these two radionuclides is difficult, however, because their emission energies are close. The authors previously deve...
متن کاملQuantitative SPECT reconstruction using CT-derived corrections.
A method for achieving quantitative single-photon emission computed tomography (SPECT) based upon corrections derived from x-ray computed tomography (CT) data is presented. A CT-derived attenuation map is used to perform transmission-dependent scatter correction (TDSC) in conjunction with non-uniform attenuation correction. The original CT data are also utilized to correct for partial volume ef...
متن کاملSinus Tarsi Syndrome: Diagnosed on 99m-Tc MDP Bone SPECT/CT
Sinus Tarsi Syndrome is a cause of chronic ankle instability and pain. MRI of the ankle has been the modality of choice for diagnosing the condition. However, SPECT-CT offers an alternate modality for diagnosing and evaluation of the condition. We present the case of a footballer who was suffering from chronic right leg pain despite receiving physiotherapy. He was being managed as a case of a c...
متن کاملShort communication Quantitative simultaneous Tc-ECD/I-FP-CIT SPECT in Parkinson’s disease and multiple system atrophy
Purpose: The purpose of this study was to investigate the feasibility and utility of dual-isotope SPECT for differential diagnosis of idiopathic Parkinson’s disease (IPD) and multiple system atrophy (MSA). Methods: Simultaneous Tc-ECD/I-FP-CIT studies were performed in nine normal controls, five IPD patients, and five MSA patients. Projections were corrected for scatter, cross-talk, and high-en...
متن کاملA study of SPECT/CT camera stability for quantitative imaging
BACKGROUND The purpose of this study was twofold: to evaluate the quantitative stability of a SPECT/CT gamma camera over time and to determine if daily flood acquisitions can reliably serve as calibration factors for quantitative SPECT. Using a cylindrical water phantom filled with measured amounts of (99m)Tc, factors were calculated to convert counts/cc to activity/cps. Measurements were made ...
