Introduction: Lymphoscintigraphy is an imaging technique to diagnose and characterize the severity of edema in upper and lower extremities. In lymphoscintigraphy a scoring system can increase ability of diagnostic differentiation but the use of any scoring system requires sufficient reliability. AIM: To determine inter- and intraobserver reliability of a proposed scoring system used for visual interpretation of lymphoscintigraphic imaging of lower extremities. Materials and Methods: Lymphoscintigrams in 81 persons were randomly selected from our database for retrospective evaluation...

Objective: This study aimed to determine whether a bismuth-coated latex shield (B-shield) could protect the eyes during brain SPECT/CT. Methods: A B-shield containing the heavy metal bismuth (0.15 mm lead equivalent) was placed over a cylindrical phantom and the eyes of a three-dimensional brain phantom filled with Tc-99m solution. Subsequently, phantoms with and without the B-shield were compared using SPECT/CT. The CT parameters were 30-200 mA and 130 kV. The dose reduction achieved by the B shield was measured using a pencil-shaped ionization chamber...

Since the early 2000's, evaluation of pulmonary embolism (PE) has shifted from (99m)Tc macroaggregated albumin (MAA) perfusion lung scans to CT angiography (CTA). (99m)Tc MAA continues to be used in patients with contraindications to CTA and for other uses. A reduced number of MAA particles is used in patients with pulmonary hypertension (PH) or other risk factors. This study assessed the changing use patterns for (99m)Tc MAA by comparing snap-shots of procedures in 2000 and in 2015 in one institution. Methods: Records for all patients receiving (99m)Tc MAA in the year 2000 and in 2015 were reviewed, making note of the imaging procedure, any contraindication to CTA, and if a reduced number of MAA particles was used...

We submitted this study to describe the pattern of contamination of the collimator and motion artifact, and measures needed for its identification and confirmation, to emphasise the importance of detection of potential sources of false positive results associated with the nuclear scans. It is important for the nuclear medicine technologist and physicians to recognize the various patterns of sources of error associated in a specific study in order to avoid the unnecessary radiation exposure to the patients (according to the ALARA)...

Planar perfusion scintigraphy with Tc99m-labelled macroaggregated albumin (Tc99m-MAA) is often used for pre-therapy quantification of regional lung perfusion in lung cancer patients, particularly in patients with poor respiratory function. However, subdividing lung parenchyma in rectangular regions of interests, as done on planar images, is a poor reflection of true lobar anatomy. New tridimensional methods using SPECT and SPECT/CT have been introduced, including a semi-automatic lung segmentation software (Hermes Medical Solutions)...

REVIEW
Ajay Kumar, Harry T Chugani
PET and SPECT can play an important role in the evaluation of various epileptic syndromes, particularly those with unknown causes, by revealing various underlying abnormalities that may not be fully appreciated from MR imaging studies. In some cases, PET and SPECT provide crucial data that guide surgical resections of the epileptogenic zone for medically refractory epilepsy. In other cases, these neuroimaging modalities preclude a surgical option and can guide genetic studies. Longitudinal PET and SPECT studies may increase our understanding of the etiopathogenesis of epilepsy syndromes and provide a clearer picture of the natural history of neurologic progression...

REVIEW
Ajay Kumar, Harry T Chugani
Epilepsy is one of the most common yet diverse neurologic disorders, affecting almost 1%-2% of the population. Presently, radionuclide imaging such as PET and SPECT is not used in the primary diagnosis or evaluation of recent-onset epilepsy. However, it can play a unique and important role in certain specific situations, such as in noninvasive presurgical localization of epileptogenic brain regions in intractable-seizure patients being considered for epilepsy surgery. Radionuclide imaging can be particularly useful if MR imaging is either negative for lesions or shows several lesions of which only 1 or 2 are suspected to be epileptogenic and if electroencephalogram changes are equivocal or discordant with the structural imaging...

Many variables can influence the results of gastric emptying scintigraphy (GES). A lack of methodologic standardization may cause variability, limit comparisons, and decrease the credibility of the test. To address this, in 2009, the Society of Nuclear Medicine and Molecular Imaging (SNMMI) published a procedure guideline describing a standardized, validated GES protocol for adults. Laboratories must closely follow the consensus protocol to provide valid and standardized results and improve patient care. The Intersocietal Accreditation Commission (IAC) evaluates compliance with guidelines as part of the accreditation process...

Glomerular filtration rate (GFR) measurements are critical in patients with hepatic cirrhosis but potentially erroneous when based on serum creatinine. New equations for estimated GFR (eGFR) have shown variable performance in cirrhotics, possibly because of inaccuracies in reference methods for measured GFR (mGFR). The primary objective was to compare the performance of 4 improved eGFR equations with a 1-compartment, 2-sample plasma slope intercept (99m)Tc-DTPA mGFR method to determine whether any of the eGFR calculations could replace plasma (99m)Tc-DTPA mGFR in patients with cirrhosis...

Our aim was to comparatively assess dual-tracer PET/CT ((68)Ga-DOTATATE and (18)F-FDG) and multimodality anatomic imaging in studying metastatic neuroendocrine tumors (NETs) of unknown primary (CUP-NETs) scheduled for peptide receptor radionuclide therapy for divergence of tracer uptake on dual-tracer PET/CT, detection of primary, and overall lesion detection vis-a-vis tumor proliferation index (MIB-1/Ki-67). Methods: Fifty-one patients with CUP-NETs (25 men, 26 women; age, 22-74 y), histopathologically proven and thoroughly investigated with conventional imaging modalities (ultrasonography, CT/contrast-enhanced CT, MRI, and endoscopic ultrasound, wherever applicable), were retrospectively analyzed...

Although prior studies showed that patients with cirrhosis have a lower risk of developing liver metastases, appropriate workup of incidental liver masses in cirrhotic liver is important for a correct diagnosis. Here we present a case of newly diagnosed liver cirrhosis with multifocal hepatic lesions, which was initially categorized as a LI-RADS (Liver Imaging Reporting and Data System) 5 lesions. Scintigraphy with (111)In-pentetreotide (Octreoscan) indicated a suspected thyroid nodule, later confirmed to represent medullary thyroid carcinoma lesion...
