Kappas, D.A. BradleyAbstractDuring the preparation of radioisotopes, during their administration and during patient imaging nuclear medicine personnel are routinely exposed to ionising radiation. With radiation risks increasing with dose, safety assessment is required in seeking to ensure practice complies with international guidelines and dose limits. A particular aim herein is to measure staff exposures during certain molecular imaging procedures including through use of positron emission tomography with computed tomography (PET/CT) and single photon emission computed tomography (SPECT) procedures. Over a one-year period occupational doses were monitored for 30 nuclear medicine personnel at King Faisal Specialist Hospital and Research Center (KFSH&RC) in Riyadh. Dose equivalent values were measured in terms of Hp (10) (deep dose) and Hp (0.07) (skin dose), extremity doses also being measured via ring dosimeters. The measurements were made using calibrated thermoluminescent dosimeters, type LiF:Mg, Ti (TLD-100). In mSv, the respective mean annual dose and range for Hp (10), Hp (0.07) and extremities were 3.05 ± 2.1 (0.23–0.91), 3.15 ± 2.2 (0.1–9.9) and 28.25 (0.1–298.0). In all cases, extremity dose values were well below the annual dose limi...

Authors: Brindhaban A Abstract Rationale: Radiation dose to patients from imaging modalities are measured or calculated to assess the risk of the procedure and compared it to the benefits. Periodic review of image acquisition methods and radiation dose used are essential part of procedure optimization in medical imaging. The aim of this study was to estimate patient radiation dose from single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) using computed tomography (CT) images for attenuation correction. Methods: SPECT and CT image acquisition parameters such as, administered activity...

Authors: Loudos G, Georgiou M, Rouchota M, Papadimitroulas P, Fysikopoulos E Abstract BACKGROUND: For every new drug,>10,000 candidate molecules are tested for ~15 years. This is the daily mission of thousands research teams worldwide. It is well proven that small animal imaging speeds up this work, increases accuracy and decreases costs. However, commercial imaging systems have high purchase cost, require high service contracts, special facilities and trained staff. Thus, they are affordable to only few large research centres and not to the majority of small and medium research teams internationally. There are ...

CONCLUSION: The low agreement between amyloid PET/CT and previous clinical and instrumental assessments that we found in our study suggests that the amyloid PET/CT provides additional and early information. To perform an early and differential diagnosis of AD could have a great impact on the patient's management and cost of care in order to perform the correct therapeutic interventions and to allow family members to manage adequately the patient's demanding care.

Abstract Positron emission tomography (PET) and single photon emission computed tomography (SPECT) are powerful molecular imaging methods for examining disease-related factors in the whole body using specific imaging probes. Recently, we tried to develop molecular imaging probes that specifically visualize pathological factors associated with cancers and infectious diseases. Although survivin is highly expressed in several cancers, its expression is undetectable in non-dividing tissues. Thus, we developed several small molecular imaging probes that target survivin. These ligands not only showed high affinity for s...

Abstract Background: Functional assessment to rule out myocardial ischemia using coronary computed tomography angiography (CCTA) is extremely important and data on the Brazilian population are still limited. Objective: To assess the diagnostic performance of myocardial perfusion by CCTA in the detection of severe obstructive coronary artery disease (CAD) compared with single-photon emission computerized tomography (SPECT). To analyze the importance of anatomical knowledge to understand the presence of myocardial perfusion defects on SPECT imaging that is not identified on computed tomography (CT) scan. Method: A total of 3...

CONCLUSION: DAT-SPECT has been well documented to be highly diagnostically accurate and to have a relevant influence on the diagnosis and treatment of patients with clinically uncertain parkinsonian or tremor syndrome. It has not yet been shown to improve patient-relevant endpoints such as mortality, morbidity, and health-related quality of life; proof of this will probably have to await the introduction of neuroprotective treatments. The current evidence for the high differential diagnostic accuracy of FDG-PET in neurodegenerative parkinsonian syndromes needs to be reinforced by prospective studies with neuropathological ...

Haldorsen Endometrial cancer is the most common gynecologic malignancy in industrialized countries. Most patients are cured by surgery; however, about 15% of the patients develop recurrence with limited treatment options. Patient-derived tumor xenograft (PDX) mouse models represent useful tools for preclinical evaluation of new therapies and biomarker identification. Preclinical imaging by magnetic resonance imaging (MRI), positron emission tomography-computed tomography (PET-CT), single-photon emission computed tomography (SPECT) and optical imaging during disease progression enables visualization and quantification o...

AbstractWhile molecular imaging with positron emission tomography or single-photon emission computed tomography already reports on tumour molecular mechanisms on a macroscopic scale, there is increasing evidence that there are multiple additional features within medical images that can further improve tumour characterization, treatment prediction and prognostication. Early reports have already revealed the power of radiomics to personalize and improve patient management and outcomes. What remains unclear is how these additional metrics relate to underlying molecular mechanisms of disease. Furthermore, the ability to deal w...

The objective of this review is to discuss current modalities and devices as well as highlight promising advancements intended to aid in diagnosing secondary lymp hedema in breast cancer patients.Recent FindingsImaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) can offer high resolution of the lymphatics but are expensive and time-consuming. Single photon emission computed tomography (SPECT) is an alternative that reveals organ function as opposed to organ structure. Other imaging methods, such as color duplex ultrasound (CDU), laser scanner 3D (LS3D), and dual-energy X-ray absorptiome...
