UNLABELLED A variety of diagnostic tools including biochemistry, radiological imaging bone marrow studies and recently metabolic imaging with FDG PET are used for assessment of disease extent in myeloma. AIM To evaluate the role of metabolic imaging with Tc99m Sestamibi (Mibi) SPECT-CT in Multiple myeloma. MATERIALS AND METHODS Patients in various stages of Myeloma were scanned after 20mCi ...

A 31-year-old woman visited an out-patient clinic, because of low-grade fever and general fatigue. She was referred to our hospital and admitted for examination of an abnormal shadow which had been found on the chest radiograph. She had experienced faint right lateral chest pain several times on the deep inspirations. Chest radiography showed a mass shadow with calcification in the right lower ...

We report a three-phase bone scintigraphy for the diagnosis of a peripheral bone lesion caused by systemic sarcoidosis. A 32-year-old man with suspected osteomyelitis of the right forefinger underwent three-phase bone scintigraphy with Tc-99m hydroxymethylene diphosphonate (HMDP) and single-photon emission computed tomography/computed tomography (SPECT/CT). The lesion was rich in blood flow acc...

The new potential tracer of bone imaging, AHBDP-Sn(II)-TcO.3H(2)O was synthesized by reducing the TcO(4) (-) to TcO(2) (+) in the presence of AHBDP and Sn(ll)'s reducing agent. We found that tin rapidly forms a stable complex with AHBDP, giving AHBDP-Sn(II).3H(2)O. In the excess of AHBDP-Sn(ll).3H(2)O, the AHBDP-Sn(II).3H(2)O coordinates with TcO(2) (+) to give AHBDP-Sn(II)-TcO.3H(2)O which cou...

Polymeric micelle of the A₃B-type lactosome comprising (poly(sarcosine))₃-b-poly(l-lactic acid) was labeled with 111In. The 111In-labeled A₃B-type lactosome was administered to the model mice bearing meningeal dissemination and bone metastasis at mandible. With single-photon emission computed tomography (SPECT) imaging, the meningeal dissemination was identified successfully by 111In-labeled A₃...

We present the domain-independent HRFF algorithm, which solves goal-oriented HMDPs by incrementally aggregating plans generated by the Metric-FF planner into a policy defined over discrete and continuous state variables. HRFF takes into account non-monotonic state variables, and complex combinations of many discrete and continuous probability distributions. We introduce new data structures and ...

Acute lymphoblastic leukemia (ALL) has several clinical manifestations on the base of bone marrow infiltration and the extent of extra medullary involvement. Anterior chest wall bulging as an initial presentation is rare. The aim of this case report study is to present a 3.5 year-old-boy presented with anterior chest wall bulging without history of trauma since 1 month ago. Tc99m-MDP bone scan ...

To assess cortical activity during pain perception, regional cerebral blood flow (rCBF) studies were done in humans using single photon emission computed tomography (SPECT) with the radiotracer Tc99m-HMPAO and magnetic resonance imaging localization. Normalized SPECT data were analyzed by region of interest and change distribution. Contralateral somatosensory rCBF was decreased when the digits ...

The aim of this in vitro study was to evaluate the possible interference of a Nectandra membranacea extract (i) on the labeling of blood cells (BC), (ii) on the labeling process of BC and plasma (P) proteins with technetium-99m (Tc-99m) and (iii) on the morphology of red blood cells (RBC). Blood samples were incubated with a Nectandra membranacea crude extract, stannous chloride, Tc99m (sodium ...
