Single photon emission computed tomography (SPECT) with 201TIC1 was performed in 27 patients with brain tumors. Findings on SPECT were compared with those on planar images, computed tomography (CT) and, in 4 cases, magnetic resonance imaging (MRI). At SPECT the tumors were shown as areas with higher accumulation of the tracers than the surrounding brain tissue in 24 cases and a better discrimination was obtained than in planar images. Deep-seated lesions were especially visualized. In some cases SPECT defined lesions that were not clearly delineated on CT or MRI. SPECT with 201TlCl can be of clinical use in the diagnosis of brain tumors.

D001932 Brain Neoplasms Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.

D015899 Tomography, Emission-Computed, Single-Photon A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.
