Comparison of planar bone scintigraphy and single photon emission computed tomography in patients suspected of having unilateral condylar hyperactivity

Comparison of different analytical methods used for analyzing SPECT scans of patients with unilateral condylar hyperactivity

“…In recent literature, several bone scanning methods, varying from simple planar bone scanning to more sophisticated methods such as SPECT, have been described for evaluating asymmetrical mandibles 2,6,[9][10][11] . In the case of UCH, rather than planar bone scintigraphy, SPECT scanning appears to be a significantly better diagnostic tool 2,9,13 . Several methods for SPECT analysis are described in international literature.…”

Microcomputed tomographic analysis of human condyles in unilateral condylar hyperplasia: increased cortical porosity and trabecular bone volume fraction with reduced mineralisation

“…10,11 There were 10 female and 7 male patients, mean age (range) at the time of operation of 22 (10-39) years. All patients were treated by high condylectomy -that is, removal of the upper 5-8 mm of the mandibular condyle (6 right and 11 left).…”

Bone scintigraphy as a diagnostic method in unilateral hyperactivity of the mandibular condyles: a review and meta-analysis of the literature

“…The planar bone scanning technique was used in 8 studies 1,3,7-9,11,25,26 , SPECT scanning in 1 study 22 and a combination in 4 studies 2,12,21,29 . In 2 studies 18,30 , the scanning technique used was not specified.…”

“…Seven studies 1,9,11,12,22,25,29 presented results in enough detail (i.e. number of patients with presence/absence of UCH and number of abnormal and normal bone scan results) to calculate the index test characteristics (i.e.…”

“…Two frequently used scanning techniques are planar bone scanning and single photon emission computed tomography (SPECT), both of which use the same basic technology. SPECT produces a tomographic bone scan image that may be more reliable than planar scanning 12,21,29 . The 2 scanning techniques can be analyzed in a qualitative (subjective) and quantitative (objective) manner.…”
