Introduction In 2016, our center adopted technology to routinely monitor 18 F-FDG radiopharmaceutical administrations. Within six months of following basic quality improvement methodology, technologists reduced extravasation rates from 13.3% 2.9% ( p < 0.0001). These same administer other radiopharmaceuticals (without monitoring technology) for general nuclear medicine procedures in a se...

Technetium-99m radiopharmaceuticals play an important role in wide range of applications in nuclear medicine. Bone imaging agents are among the fi rst developed 99mTc-radiopharmaceuticals and the most widely used radiopharmaceuticals in diagnostic nuclear medicine [1]. Bisphosphonates (BPs) are synthetic organic compounds characterized by a P-C-P backbone structure. They are chemically stable a...

Mastocytosis is a rare, heterogeneous disease of complex etiology, characterized by a marked increase in mast cell density in the skin, bone marrow, liver, spleen, gastrointestinal mucosa and lymph nodes. The most frequent site of organ involvement is the skin. Cutaneous lesions include urticaria pigmentosa, mastocytoma, diffuse and erythematous cutaneous mastocytosis, and telangiectasia macula...

A 40-year-old man presented with decreased mental ability and acute renal failure. He had played computer games for 3 days without rest and proper oral intake before coming to our hospital. On admission, serum creatinine was 10.1mg/dl. Urinalysis showed dysmorphic red blood cell (16–20/HPF) and proteinuria. Serum creatinine kinase was 13 840U/l (normal range, 5–217) and serum myoglobin was 8621...

A report is presented of a liquefaction necrosis of mitral annular calcification in a patient with chronic renal failure and secondary hyperparathyroidism who had been managed by hemodialysis for 11 years. The mass was echogenic with an echo-lucent area inside, high density on computed tomography and low intensity on magnetic resonance imaging. The uptake of gallium-67 (67Ga)-citrate and the bo...

CONTEXT Non-small cell lung carcinomas (NSCLCs) of the superior sulcus are considered to be the most challenging type of malignant thoracic disease. In this disease, neoplasms originating mostly from the extreme apex of the lung expand to the chest wall and thoracic inlet structures. Multiple imaging procedures have been applied to identify tumors and to stage and predict tumor resectability in...

A 59-year-old man presented with a 7-month history of increasing left shoulder pain. The initial plain films showed near absence of the left scapula and scattered lucent changes in the left humerus. A CT scan confirmed the presence of widespread lytic bony lesions, with a large soft-tissue mass centered around the left scapula. An isotope bone scan demonstrated marked uptake of MDP in the stoma...

AIM The accuracy of bone scintigraphy in diagnosing symptomatic accessory navicular bones has not been well studied. We conducted a retrospective study to explore the results and use of scintigraphy in symptomatic and asymptomatic accessory navicular bones. MATERIALS AND METHODS Thirteen patients with a total of 13 symptomatic and 10 asymptomatic accessory navicular bones were included in the...
