AIM The goal of the study is to correlate serum calcium levels with the results of dual-phase (99m)Tc-sestamibi parathyroid scintigraphy to find the best cut-off level of the serum calcium that correlates with a positive presurgery. METHODS In 111 patients, serum calcium and plasma parathormone (PTH) levels were compared with the results of the (99m)Tc-MIBI scintigraphy and with this data det...

bone involvement. Destruction is mediated through normal osteoclasts, which respond to local osteoclast-activating microenvironment [7]. Technetium-99m 2methoxyisobutylisonitrile (TC-99m MIBI) is a lipophilic agent that accumulates within living malignant cells due to the higher transmembrane electrical potential as a consequence of the higher metabolic rate than in the surrounding normal cells...

Introduction: 99mTc-Methylene diphosphonate (99mTc-MDP) three phase bone scintigraphy (TPS) is beneficial to evaluate the success of femoral head revascularization using novel distraction osteogenesis techniques with bone muscle pedicle grafts. This pilot study was undertaken to evaluate the feasibility and utility of 99mTc-MDP three phase bone ...

UNLABELLED Assessment of tumor viability and necrosis of non-small cell lung cancer and detection of distant metastases are important for diagnosis, staging, monitoring the response to treatment and planning long-term management. We performed scintigraphy on patients with non-small cell lung cancer to determine the utility of three tumor targeting tracers for diagnosing primary lung cancer, for...

OBJECTIVE This study aimed to present seven cases of avascular necrosis of the sesamoid and report the role of bone scintigraphy in the diagnosis of these patients. METHODS Seven patients with clinical suspicion of avascular necrosis of the sesamoid underwent three-phase bone scintigraphy with 30 mCi of (99m)Tc-MDP. RESULTS Most of the patients were young female adults with complaints of li...

Introduction: In Islamic countries in the month of Holy Ramadan many Muslims based on their religious Legislation refuse fluid intake during the fasting time though instructed to drink after injection of Tc-99m Methylene-diphosphonates [Tc-99m MDP] used for skeletal scintigraphy. We aimed to establish whether fluid restriction in Tc-99m MDP skeletal scintigraphy has an impact on its quality. M...

AIM To evaluate the role of 99m-technetium methylene diphosphonate (Tc-99m MDP) bone scintigraphy on the detection of joint damage in asymptomatic alpine ski racers. MATERIALS AND METHODS This study included 20 male asymptomatic alpine ski racers (age range: 18-21 years). None of the skiers had a history of ski crashes. Bone scan findings of the racers were examined with Tc-99m MDP bone scint...

The role of various radionuclide investigations, including parathyroid scintigraphy, bone scintigraphy and serum parathormone estimations in the diagnosis of primary hyperparathyroidism is reviewed briefly. The initial experience with the dual isotope (Tl-201; Tc-99m) subtraction scintigraphy for the preoperative localization of parathyroid adenomas is presented (JPMA 37 : 237, 1987).

BACKGROUND Radionuclide techniques, as direct radionuclide cystography and (99m)Tc-DMSA scintigraphy, have been used in evaluation of vesicoureteral reflux (VUR) and reflux nephropathy (RN) in children. Dynamic (99m)Tc-DTPA scintigraphy is reserved for evaluation of differential renal function and obstruction in children, where hydronephrosis is detected by ultrasonography (US) pre- or postnata...

  Introduction: Ubiquicidin (UBI) 29-41 is a synthetic antimicrobial peptide that binds with the microbial cell membrane at the location of infection. This study was conducted to evaluate its probable efficacy as an infection-imaging agent with potential to differentiate bacterial infection from sterile inflammation in humans. Methods: Fifteen diabetic foot patients ...
