OBJECTIVE To evaluate the usefulness of myocardial perfusion scintigraphy (MIBI-SPECT) as a diagnostic tool in well trained men. DESIGN The study was prospective, involving 2 d stress-rest myocardial scintigraphy (MIBI-SPECT), polar map reconstruction with and without uniform attenuation correction, and comparison with a healthy male group (local Swedish) and with a commonly used reference gr...

POLSKIE ARCHIWUM MEDYCYNY WEWNĘTRZNEJ 2016; 126 (3) MM is characterized by malignant proliferation of clonal plasma cells and excessive formation of monoclonal immunoglobulin.1 99mTc-MIBI is a radiotracer commonly used in myocardial perfusion imaging (FIGURE 1C). In literature, there have been reports on the use of 99mTc-MIBI in the diagnosis of MM since 1996.2 In a multicenter study conducted ...

The Authors Reply A physical examination, laboratory test and computed tomography scan revealed sensorineural hearing loss, cerebellum atrophy, exophoria and intellectual disability. There was no involvement of the eye, gastrointestinal tract, kidney, bone marrow or skin. Unfortunately, we did not perform a biopsy of any tissues other than the myocardium and so cannot compare the heteroplasmy r...

The use of technetium-99m 2-methoxyisobutyl isonitrile ((99m)Tc MIBI) for assistance in minimally invasive radioguided surgery (MIRS) is growing in popularity as a safe, effective, and proficient technique used for parathyroidectomy in primary hyperparathyroidism (PHPT) treatment. Previously, the preferred treatment for PHPT was bilateral neck exploration (BNE), a very invasive, costly, and len...

A 76-year-old dialysis patient developed sudden pain in his left arm. He consulted an orthopaedic surgeon who determined a fractured left humerus with an osteolytic lesion (Figure 1). The patient was referred to our department for further evaluation of a possible osteoscarcoma. He had required haemodialysis treatment for 4 years because of an unknown renal disease that left him with small end-s...

Secondary hyperparathyroidism (sHPT) is one of the most common and serious complications of chronic kidney disease (CKD) and maintenance hemodialysis (MHD). In sHPT, the biology of parathyroid cells changes significantly toward diffuse and nodular hyperplasia. Diagnosis and treatment of sHPT are based on intact parathyroid hormone (i-PTH) serum levels and on the parameters of mineral metabolism...

UNLABELLED (99m)Tc-sestamibi dual-phase scintigraphy is currently established for parathyroid localization. However, the imaging technique is not standardized, and the role of the pinhole collimator, especially, is not fully recognized in the imaging protocol. The aim of this study was to check whether the use of a pinhole collimator in parathyroid scintigraphy would enhance lesion detectabilit...
