a 36-year-old woman with right upper quadrant abdominal pain since three months previously and no other significant medical history was referred for evaluation of an abdominal mass. upon clinical examination, a large palpable mass in the mid -upper abdominal area was noted. abdominal ultrasound and spiral ct-scan showed a large hepatic mass in the left liver lobe. the patient was referred for t...

Objective(s): BONENAVI, a computer-aided diagnostic system, is used in bone scintigraphy. This system provides the artificial neural network (ANN) and bone scan index (BSI) values. ANN is associated with the possibility of bone metastasis, while BSI is related to the amount of bone metastasis. The degree of uptake on bone scintigraphy can be affected by the type of bone metastasis. Therefore, t...

BACKGROUND The detection of occult bone metastases is a key factor in determining the management of patients with renal cell carcinoma (RCC), especially when curative surgery is considered. This prospective study assessed the sensitivity of (18)F-labelled sodium fluoride in conjunction with positron emission tomography/computed tomography ((18)F-NaF PET/CT) for detecting RCC bone metastases, co...

Background: Local ablative treatments play an important role for patients who cannot be treated surgically. Radiofrequency ablation is a well-established alternative to surgical treatment of thyroid nodules, however it also has disadvantages. Microwave ablation (MWA) is a new minimally invasive treatment promising several improvements. The aim of this retrospective study was to evaluate the eff...

OBJECTIVE Our aim was to evaluate whether high-resolution sonography can provide additional information concerning rib lesions compared with radiography or bone scintigraphy. MATERIALS AND METHODS Fifty-eight patients with high-uptake rib lesions seen on bone scintigraphy were selected. Radiography and rib high-resolution sonography were performed on these patients. High-resolution sonography...

Axillary or elbow lymph node visualization after subcutaneous infiltration of the bone-imaging agent on a routine bone scintigraphy has been reported. The prostate cancer patient in this case report underwent bone scintigraphy; in 3-h bone images, the lymph nodes in the wrist, elbow, and axillary regions were simultaneously visualized. This was caused by extravasation of the intravenous injecti...

AIM The bone scintigraphy is indicated in patients with costochondral pain in order to identify the organic etiology. We aimed to investigate the local and projecting pain, or incidental findings in the three phase bone scintigraphy of the patients referred for costochondral pain. METHODS We included 50 patients (36F, 24M; mean: 41±18 years-old) referred to our department for three phase bone...

BACKGROUND/AIM Bone scintigraphy is well-known method for the detection of neoplastic lesions with a high sensitivity and, at the same time, a lower specificity. On the other hand magnetic resonance imaging (MRI) is previously established noninvasive imaging method regar ding its diagnostic specificity. The aim of this study was to determine the possibilities and to correlate two different diag...

BACKGROUND Positron emission tomography (PET) with 18-F-fluorodeoxyglucose (FDG) has already proved useful in assessing the extension of esophageal carcinomas, detecting tumor recurrence and monitoring responses to therapy. This study aimed to elucidate the potential role of FDG-PET compared with technetium-99m methylene diphosphonate (Tc-99m MDP) bone scintigraphy in the evaluation of bony met...

BACKGROUND AND PURPOSE Radiologic evaluation of CSF leaks is a diagnostic challenge that often involves multiple imaging studies with the associated expense and patient discomfort. We evaluated the use of screening noncontrast high-resolution CT in identifying the presence and site of CSF rhinorrhea and otorrhea and compared it with contrast-enhanced CT cisternography and radionuclide cisternog...
