Background Myocardial ischaemic burden assessed by myocardial perfusion scintigraphy (MPS) is commonly used to riskstratify patients with suspected coronary artery disease (CAD). Accurate estimation of ischaemic burden by CMR with two-dimensional imaging is limited by incomplete myocardial coverage to a small number (usually three) of non-contiguous sections. The aim of this study was to compar...

In this chapter, we review different imaging modalities, including radiography, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and nuclear medicine scintigraphy, and their application to musculoskeletal neoplasm. Advantages and limitations of each modality are reviewed, and suggestions for imaging approach are provided.

Purpose: To identify and interrogate the role of Gallium-67 scintigraphy in the diagnosis of Sarcoidosis. Methods: A retrospective study of 75 patients with suspected Sarcoidosis in a large teaching hospital with a specialist Sarcoidosis Centre. Results: Ga-67 scintigraphy in patients considered on clinical grounds to have Sarcoidosis is a useful and sensitive test, and furthermore, by relaxing...

PURPOSE We aimed to assess the role of single photon emission computed tomography-computed tomography (SPECT-CT) for characterizing isolated vertebral lesions observed by bone scintigraphy compared to planar scintigraphy, SPECT, and CT, and to evaluate the impact of SPECT-CT on patient management. MATERIALS AND METHODS Data from 99 patients (mean age, 52.4±18.9 years; females, 58.5%) with 108...

Radiologic imaging of the newborn detected prenatally with hydronephrosis should follow a systematic approach. Upper and lower urinary tract imaging should be performed in most cases in order to determine the etiology and gauge the use of future imaging. An overview of renal ultrasound, voiding cystourethrography, renal scintigraphy, and magnetic resonance urography in the setting of antenatal ...

The main propose of this approach is to evaluate the efficiency of Tc-Ciprofloxacin (Infecton) imaging to detect infection sites induced in foot’s rat by staphylococcus aureus susceptible to ciprofloxacin in comparison with S aureus resistant to drug. S aureus bacteria have been isolated from the patients admitted in Imam Khomeini hospital Ahvaz Khuzestan Iran. According to the table of Clinica...

•Splenosis can mimic carcinomatosis upon many imaging modalities.•History of splenectomy must be considered when evaluating carcinomatosis.•Scintigraphy is the preferred for confirming the presence of splenosis.

Carcinoid is a neuroendocrine neoplasm derived from primitive stem cells, occurring most frequently in the alimentary tract. Somatostatin-receptor scintigraphy with indium-111 pentetreotide is a sensitive and noninvasive technique for imaging carcinoid and its metastatic spread. However, nontumoral lesions such as sarcoidosis may also express somatostatin receptors, which may present a diagnost...

(99m)Tc-galactosyl human serum albumin (GSA) scintigraphy is useful to evaluate hepatic function and hepatic functional reserve. A reliable SPECT and CT integrated system is now commercially available. Using this system, we can obtain (99m)Tc-GSA SPECT/CT fused imaging with a small registration error. Therefore, the (99m)Tc-GSA scintigraphy techniques prove more useful in clinical practice than...

In view of the commercial success of integrated PET/CT scanners, there is an increasing interest in comparable SPECT/CT systems. SPECT in combination with CT enables a direct correlation of anatomic information and functional information, resulting in better localization and definition of scintigraphic findings. Besides anatomic referencing, the added value of CT coregistration is based on the ...
