Prevalence of transthyretin cardiac amyloidosis in patients with aortic stenosis.

Background: Transthyretin cardiac amyloidosis (ATTRCA) is a prevalent disease, and it can be associated with heart failure (HF), left ventricle hypertrophy (LVH), atrial fibrillation (AF), and aortic stenosis (AS).

Aim: The study aims to detect the prevalence of ATTRCA in the symptomatic AS population.

Method: A single-center prospective study screening for ATTRCA in patients diagnosed with symptomatic severe AS undergoing aortic valve (AV) intervention.

Best Practices in Nuclear Imaging for the Diagnosis of Transthyretin Amyloid Cardiomyopathy (ATTR-CM) in KSA: The Eagle Eyes of Local Experts.

Transthyretin amyloid cardiomyopathy (ATTR-CM) is a complex and serious form of heart failure caused by the accumulation of transthyretin amyloid protein in the heart muscle. Variable symptoms of ATTR-CM can lead to a delayed diagnosis. Recognizing the diagnostic indicators is crucial to promptly detect this condition.

Rare sites of metastases in patients with differentiated thyroid carcinoma and added value of SPECT/CT over planar whole body radioactive iodine scan.

Background: Being aware of the unusual or rare location of thyroid metastases helps in early diagnosis and proper patient management. Rare metastases (RM) can be missed resulting in diagnostic pitfalls and delayed treatment. The use of single-photon emission computed tomography/computed tomography (SPECT/CT) imaging in the follow-up of differentiated thyroid cancer (DTC) patients provides precise anatomical localization and characterization of RM that may be missed or misinterpreted in planar whole body iodine-131 (WBI) scan.

Characteristics of malignant thyroid lesions on [F] fluorodeoxyglucose (FDG)-Positron emission tomography (PET)/Computed tomography (CT).

Objectives: To determine the imaging variables that can best differentiate malignant from benign thyroid lesions incidentally found on F-18 FDG PET/CT scans.

Methods: All F-18 FDG PET/CT studies starting from 2011 to end of 2016 were reviewed for incidental thyroid lesions or metabolic abnormalities. Only patients who were found to have FNAB or histopathology were included.

Assessment of risk factors for bone fractures in patients with type 2 diabetes mellitus: A study in Saudi Arabia.

Background And Aims: This study aimed to estimate the prevalence of bone fractures and analyze their associated risk factors in people with and without type 2 diabetes (T2D) in Saudi Arabia.

Methods: This study was conducted among 1188 people (581 type 2 diabetes) in Prince Sultan Military Medical City, Riyadh, Saudi Arabia. In addition to the demographic variables, glycated hemoglobin (HbA1c), creatinine, estimated glomerular filtration rate (eGFR), use of teriparatide, presence of rheumatoid arthritis, presence of chronic obstructive pulmonary disease (COPD), Bone mineral density (BMD), Trabecular Bone Score (TBS) and Fracture Risk using the Fracture Risk Assessment Tool (FRAX) were also collected.

Dual time point [18F]Flurodeoxyglucose (FDG) Positron Emission Tomography (PET)/Computed Tomography (CT) with water gastric distension in differentiation between malignant and benign gastric lesions.

Objectives: To assess diagnostic accuracy and added value of dual time point F-FDG PET/CT after gastric distention using oral water in differentiating malignant from benign gastric lesions.

Methods: Patients (n = 30, 19 males, mean age 58.6 ± 16.

Atypical diffuse bilateral cystic lung changes secondary to erlotinib treatment in a patient with metastatic non-small cell lung carcinoma: A case report and literature review.

Erlotinib is a first-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) approved in the first-line treatment of advanced non-small-cell lung cancer (NSCLC) patients with sensitizing epidermal growth factor receptor (EGFR) mutations. The response rate to erlotinib is ~60% and the incidence of erlotinib-induced interstitial lung disease (ILD) is ~1-4%. The Response Evaluation Criteria in Solid Tumours (RECIST) tool is commonly used to assess response to erlotinib; however, evaluation of response and subsequent progression in the presence of atypical cystic lung changes may be challenging.

Are there radiographic, metabolic, and prognostic differences between cavitary and noncavitary nonsmall cell lung carcinoma? A retrospective fluorodeoxyglucose positron emission tomography/computed tomography study.

Aims: The prognosis of nonsmall cell lung cancer with cavitation (NSCLC-c) is not well-known. We compared the positron emission tomography/computed tomography (PET/CT) findings and survival data of patients with NSCLC-c patients with those without cavitation (NSCLC-nc).

Methods: Between 7/2004 and 6/2007, cavitary lung lesions were identified in 46/248 patients undergoing fluorodeoxyglucose (FDG) PET/CT for lung nodule characterization or lung cancer staging.

Impact of nocturnal sleep deprivation on declarative memory retrieval in students at an orphanage: a psychoneuroradiological study.

Background And Methods: This study investigated the effects of sleep deprivation on total and partial (early and late) declarative memory and activation in the areas of the brain involved in these activities. The study included two experiments. Experiment 1 included 40 male residents of an orphanage aged 16-19 years, who were divided into four groups (n = 10 each) and subjected to total sleep deprivation, normal sleep, early-night sleep deprivation, or late-night sleep deprivation.

F-18 fluorodeoxyglucose positron emission tomography and/or computed tomography findings of an unusual breast lymphoma case and concurrent cervical cancer: a case report.

Introduction: Breast lymphoma accounts for less than 1% of all non-Hodgkin's lymphomas and approximately 0.1% of all breast neoplasms. Most breast lymphomas are classified as diffuse large B-cell lymphomas or as mucosa associated lymphoid tissue lymphomas.

Whole-body 18F-FDG PET/CT: the need for a standardized field of view--a referring-physician aid.

Unlabelled: PET/CT fusion of anatomic and functional imaging modalities is in evolution, with rapid clinical dissemination. The imaged field of view (FOV) selected for whole-body PET/CT protocols is not standardized and varies by institution. Misuse of the term whole body, as well as the pressure to increase the number of daily studies by reducing scanning time, contributes to the lack of standardization.

F-18 FDG PET/CT characterization of talc pleurodesis-induced pleural changes over time: a retrospective study.

Purpose: The current study characterized pleural changes induced by talc pleurodesis (TP), based on serial positron emission tomography/computer-tomography (PET/CT) with F-18 fluorodeoxyglucose (FDG).

Materials And Methods: A total of 8 cancer patients who had both TP and PET/CT and no evidence of active pleural involvement after TP were retrospectively evaluated. Maximum standard uptake values, maximum Hounsfield units (HU), and thickness were followed over time.
