This study was aimed at determining whether the ordered-subset expectation maximum (OSEM) is more effective than filtered backprojection (FBP) for bone SPECT in the routine clinical context. Methods. Fifty-seven consecutive bone SPECT studies were analyzed. They included pelvic and lumbar spine, thoraco lumbar spine, head and neck, feet and shoulders. A 64-projection SPECT study was acquired over 360° by single-head cameras 2–3h after the injection of 750 MBq 99mTc-methylene diphosphonate. Three observers compared the OSEM and FBP reconstructed images. Results. Streak artifacts, always present with FBP, were rarely generated with the OSEM. When present (n = 24), artifacts associated with negative values near hyperactivities in FBP were not generated with the OSEM in 67% of the cases (n = 16), permitting a satisfactory interpretation of these regions. In half of the other cases (17%, n = 4/24), interpretation was precluded. In only one case did the three observers agree that more hyperactivities were seen with the OSEM. Ninety-six percent of the OSEM pictures were superior or equal to FBP for anatomic resolution and were clearly better in 12% of the cases. The extent of the lesion with the OSEM seemed better or equally defined in 96% and clearly better in 14% of the cases. The low-activity regions were better or equally visualized in all cases and were clearly better seen in 23% of the cases. The quality of the pictures was found to be better or superior with the OSEM in 98% of the cases and definitely better in 65% of the cases. Conclusion: Replacement of FBP by the OSEM in bone SPECT would be beneficial to clinical practice. [less ▲]

Scintimammography performed with Tc-99m sestamibi in a 63-year-old woman with a history of mitral valve replacement and pulmonary hypertension demonstrated that the frequently observed sternal hyperactivity on anterior views could arise from the myocardium. Caution therefore should be taken before the diagnosing of any hyperactivity in the lower sternal region as a neoplastic involvement. [less ▲]
