Unexpected findings on bone scintigraphy such as asymmetrical uptake in extremities may cause confusion for the diagnosis. The authors describe three cases of accidental intraarterial injection of Tc-(99m) methylene diphosphonate ((99m)Tc-MDP) on the antecubital region and discuss the findings and differential diagnosis.
A 52-year-old woman with nonspecific left leg pain was examined by Tc-99m methylene diphosphonate (MDP) bone scintigraphy. The patient had been a marble quarry worker for 10 years and had developed chronic congestive heart failure secondary to pneumoconiosis. Her hemoglobin analysis and hematologic findings were interpreted as being consistent with sickle cell beta+ thalassemia and also hypersp...
To the Editor, We report a 52-year-old male patient with bone marrow and skeletal system involvement of sarcoidosis. In sarcoidosis, while bone involvement occurs at a rate of 10%-15%, iliac bone and bone marrow involvement is less common [1,2]. A 52-year-old male patient was admitted to our clinic with increased lower back pain with activity for the last 2 months. The patient occasionally coug...
Our lab developed (99m)Tc-NTP 15-5 radiotracer as targeting proteoglycans (PGs) for the scintigraphic imaging of joint. This paper reports preclinical results of (99m)Tc-NTP 15-5 imaging of an orthotopic model of Swarm rat chondrosarcoma (SRC). (99m)Tc-NTP 15-5 imaging of SRC-bearing and sham-operated animals was performed and quantified at regular intervals after surgery and compared to bone s...
UNLABELLED Technetium-99m dimercaptosuccinic acid (Tc-99m DMSA) as a static renal agent is currently the most frequently used agent in the detection of renal scarring, and allows accurate calculation of differential renal function (DRF). But this agent has some disadvantages such as relatively higher radiation dose and time consumption. METHODS The purpose of this study was to evaluate the po...
Cervical spinal Ewing's sarcomas are rare and cause problems in diagnosis. We present an unusual case of a primary extraosseous Ewing's sarcoma arising from the spinal cord. An 18-year-old woman with fever, headache and back pain lasting one month was admitted to the hospital. Whole body bone scintigraphy was performed with 1110 MBq technetium-99m methylenediphosphonate. Scintigraphy clearly sh...
A 27-year-old man developed polymyositis as a manifestation of chronic graft-versus-host disease (GVHD) after non-myeloablative peripheral blood stem cell transplantation (PBSCT). Bone scintigraphy showed intense, striped, and heterogeneous accumulation of Tc-99m methylene diphosphonate (MDP) in the soft-tissue of his lower limbs, while faint activities were seen in the right upper limb. Tc-99m...
Introduction: Appendicitis is one of the most common surgical emergencies. In spite of the relatively high rate of negative appendectomy, as a result of miss diagnosis, uncertainty of diagnosis still continues to challenge physicians. The objective of this prospective study was to investigate the role of 99mTc-Ubiquicidin (UBI) scintigraphy in the diagnosis of acute appendicitis and ...
UNLABELLED Diabetic foot infection is the most common etiology of nontraumatic amputation of the lower extremities, and early diagnosis is of great importance in its management. The aim of this prospective study was to evaluate the strength of (99m)Tc-IgG scintigraphy in diagnosis of osteomyelitis of the diabetic foot and to compare (99m)Tc-IgG scintigraphy with (99m)Tc-methylene diphosphonate ...
We report a case of early syphilis with multiple bone lesions which all resolved after treatment with penicillin. We discuss why bone lesions may be more prevalent than generally believed and why 99m-Tc-MDP-bone scintigraphy is more sensitive than radiography in detecting syphilitic periostitis.
