OBJECTIVES To utilize single photon emission computerized tomography performed in sequence to determine the osseo-integrating capabilities and osteoblastic activities of a new bone regeneration technique called the membrane--sandwich technique (Ogunsalu sandwich bone regenerating technique) and to compare the quality and quantity of bone formed by this bone regeneration unit to bone regeneratio...

Background: The aim of this study is to demonstrate the superiority Single Photon Emission Computed Tomography-Computed Tomography (SPECT-CT) over planar imaging in distinguishing benign from malignant foci and patient management after 131I ablation therapy patients with differentiated thyroid cancer (DTC).
 Material Methods: Planar SPECT-CT findings were retrospectively analyzed 80 who re...

BACKGROUND Image-based measurement of absorbed dose of Ra-223 dichloride may be useful in predicting therapeutic outcome in patients with castration-resistant prostate cancer (CRPC). In general, SPECT has been found to be more accurate than planar imaging in terms of lesion-based analysis. The aims of this study were to assess the feasibility and clinical usefulness of Ra-223 SPECT. The energy ...

The cause of low back pain due to lumbosacral transitional vertebra (LSTV) still remains a debated topic. Functional imaging with bone scintigraphy has been a valuable adjunct in its assessment; however, in recent years, the additional utility of single-photon emission tomography with computed tomography (SPECT/CT) is evolving as the imaging modality of choice in identifying range of complex lo...

A 26-y-old man with achondroplasia presented with chronic lower back pain with no history of trauma. MR imaging performed 5 mo previously demonstrated a congenitally small lumbar canal causing multilevel stenosis. After intravenous administration of 814 MBq (22 mCi) of 99mTc-methylene diphosphonate, delayed anterior and posterior whole-body bone scans were performed, along with spot views of th...

Extramedullary pulmonary hematopoiesis is a rare entity with a limited number of case reports in the available literature only. We report the case of a 66-year-old man with known primary myelofibrosis, in whom a Technetium-99m sulfur colloid bone marrow scan with single-photon emission computed tomography (SPECT)/CT revealed a pulmonary hematopoiesis as the cause of pulmonary hypertension and s...

Sacroiliitis is usually the first and main feature of seronegative spondyloarthropathies. But the sacroiliac joints present a problem to the diagnostician because of their deep seated location and lack of motion. This forces us to rely heavily on imaging modalities to diagnose diseases of this joint. Therefore, many imaging techniques such as computed tomography (CT); single photon emission com...
