Corticostriatal Hypermetabolism in Moyamoya Disease-Induced Hemichorea: Two Case Reports and a Literature Review.

Moyamoya disease (MMD) is a rare cause of chorea, and its pathophysiological mechanism remains unclear. We explore the use of cerebral positron emission tomography (PET) to study brain functional connectivity in 2 patients with MMD-induced hemichorea. Abnormal metabolism of brain was analyzed by F-fluorodeoxyglucose (F-FDG) PET images.

Co-registration Analysis of Fluorodopa and Fluorodeoxyglucose Positron Emission Tomography for Differentiating Multiple System Atrophy Parkinsonism Type From Parkinson's Disease.

It is difficult to differentiate between Parkinson's disease and multiple system atrophy parkinsonian subtype (MSA-P) because of the overlap of their signs and symptoms. Enormous efforts have been made to develop positron emission tomography (PET) imaging to differentiate these diseases. This study aimed to investigate the co-registration analysis of F-fluorodopa and F-flurodeoxyglucose PET images to visualize the difference between Parkinson's disease and MSA-P.

Serum Klotho, vitamin D, and homocysteine in combination predict the outcomes of Chinese patients with multiple system atrophy.

Aims: Neuroinflammation contributed to the pathogenesis of multiple system atrophy (MSA). We aimed to detect the correlation between inflammatory mediators, such as Klotho (Klt), vitamin D (25(OH)D) and homocysteine (Hcy), and disease severity among MSA patients.

Methods: A total of 53 MSA patients, 65 PD patients, and 62 normal subjects were recruited in our cross-sectional study.

Assessing the early changes of cerebral glucose metabolism via dynamic (18)FDG-PET/CT during cardiac arrest.

To study the changes of cerebral glucose metabolism (CGM) during the phase of return of spontaneous circulation (ROSC) after cardiac arrest (CA), we used 18-fluorodeoxyglucose-positron emission tomography/computed tomography ((18)FDG-PET/CT) to measure the CGM changes in six beagle canine models. After the baseline (18)FDG-PET/CT was recorded, ventricular fibrillation (VF) was induced for 6 min, followed by close-chest cardiopulmonary resuscitation (CPR) in conjunction with intravenous (IV) administration of epinephrine and external defibrillator shocks until ROSC was achieved, within 30 min. The (18)FDG was recorded prior to intravenous administration at 0 h (baseline), and at 4, 24, and 48 h after CA with ROSC.

[Comparison of (18)F-FDG PET/CT and enhancement CT in diagnosing regional lymph node metastasis of colorectal cancer].

Objective: The aim of this study was to compare the diagnostic value of (18)F-FDG PET/CT with contrast CT for regional lymph node metastasis of colorectal cancer.

Methods: Imaging results of 40 patients with colorectal cancer were retrospectively reviewed, and all the patients underwent both abdomen contrast CT and (18)F-FDG PET/CT imaging. Final diagnosis was made by histopathology.

Value of ¹⁸F-FDG-PET/CT in the detection of recurrent hepatocellular carcinoma after hepatectomy or radiofrequency ablation: a comparative study with contrast-enhanced ultrasound.

Objective: To evaluate the role of positron emission tomography/computer tomography with fluorine-18 fluorodeoxyglucose ((18) F-FDG-PET/CT) in detecting hepatocellular carcinoma (HCC) recurrence after hepatectomy and/or radiofrequency ablation (RFA) and to compare its efficacy with contrast-enhanced ultrasound (CEUS).

Methods: A total of 36 HCC patients were included in this study. All patients underwent both (18) F-FDG-PET/CT and CEUS at least once for the diagnosis of HCC recurrence.

[Diagnostic value of (18)F-labeled NaF positron emission tomography-computed tomography imaging in the detection of bone metastases in patients with lung cancer before treatment].

Objective: To evaluate the diagnostic values of (18)F-sodium fluoride ((18)F-NaF) positron emission tomography/computed tomography (PET/CT) imaging in the detection of bone metastases of lung cancer.

Methods: A total of 107 lung cancer patients were diagnosed by histopathology and undergone (18)F-NaF PET-CT imaging.

Results: Among them, the histopathologically diagnosed tumors included adenocarcinoma (n = 47), squamous cell carcinoma (n = 19), small cell lung cancer (n = 4) and other malignant types (n = 34).

[Comparison of (18)F-FDG PET-CT and abdomen enhancement CT in diagnosing peritoneal metastases].

Objective: To compare the diagnostic value of (18)F-FDG PET-CT with abdomen contrast CT in the diagnosis of peritoneal metastases.

Methods: Between January 2008 and May 2011, imaging results of 97 patients with suspicious peritoneal metastases were retrospectively reviewed, and all the patients underwent both abdomen contrast CT and (18)F-FDG PET-CT imaging. Final diagnosis was made by histopathology or follow up.

Fatality after cardiac arrest in thyrotoxic periodic paralysis due to profound hypokalemia resulting from intravenous glucose administration and inadequate potassium replacement.

Background: Thyrotoxic periodic paralysis (TPP) is a variant of periodic paralysis (PP) that occurs in patients with underlying mutations in genes for cation channels, if they develop thyrotoxicosis. It is disabling, and fatalities sometimes occur. Here, we present a patient with TPP who developed hypokalemic paralysis that was probably aggravated by the administration of a carbohydrate, probably contributing to, if not causing, a fatal outcome.

Striving for euthyroidism in radioiodine therapy of Graves' disease: a 12-year prospective, randomized, open-label blinded end point study.

Background: In China, use of radioiodine therapy is problematic because of the need for lifelong levothyroxine substitution. Our aim was to find an optimum dosing strategy for (131)I treatment of hyperthyroidism due to Graves' disease (GD). We attempted to achieve euthyroidism to avoid long-term levothyroxine treatment.
