Effect of sarcopenia and frailty on outcomes among patients with brain metastases.

Purpose: Sarcopenia and frailty have been associated with increased mortality and duration of hospitalization in cancer. However, data investigating these effects in patients with brain metastases remain limited. This study aimed to investigate the effects of sarcopenia and frailty on clinical outcomes in patients with surgically treated brain metastases.

Lymphoma Masquerading as Lung Cancer.

Lymphoma typically manifests as lymphadenopathy, with or without solid organ involvement. Lymphomatous masses tend to respect anatomical structures, encasing rather than invading them. Tumor thrombus formation is a rare presentation in lymphoma that has been previously described in the liver and kidneys.

Radiochemical Feasibility of Mixing of Tc-MAA and Y-Microspheres with Omnipaque Contrast.

Yttrium-90 (Y) microspheres are widely used for the treatment of liver-dominant malignant tumors. They are infused via catheter into the hepatic artery branches supplying the tumor under fluoroscopic guidance based on pre-therapy angiography and Technetium-99m macroaggregated albumin (Tc-MAA) planning. However, at present, these microspheres are suspended in radiolucent media such as dextrose 5% (D5) solution.

Improving Y PET Scan Image Quality Through Optimized Reconstruction Algorithms.

This study aimed to improve the quality of Y PET imaging by optimizing the reconstruction algorithm. We recruited 10 patients with neuroendocrine tumor metastatic to the liver or primary hepatocellular carcinoma who were qualified for Y-labeled selective internal radiation therapy or peptide receptor radionuclide therapy. They underwent posttherapeutic PET/CT imaging using 3 different reconstruction parameters: VUE Point HD with a 6.

The exact Deauville score, NABS score and high SUVmax predicts outcome in extranodal natural killer/T-cell lymphoma.

Objective: Natural killer T-cell lymphoma (NKTCL) is an aggressive type of non-Hodgkin's lymphoma. While FDG-PET/CT imaging has been increasingly utilized for disease assessment, its prognostic value and potential utility in NKTCL patient stratification remain controversial. We aim to investigate the prognostic utility of FDG-PET/CT and its role in complementing clinical indices.

Computed tomography coronary angiography - past, present and future.

Computed tomography coronary angiography (CTCA) is a robust and reliable non-invasive alternative imaging modality to invasive coronary angiography, which is the reference standard in evaluating the degree of coronary artery stenosis. CTCA has high negative predictive value and can confidently exclude significant coronary artery disease (CAD) in low to intermediate risk patients. Over the years, substantial effort has been made to reduce the radiation dose and increase the cost efficiency of CTCA.

Correction to: Congenital pial AVF along the falx cerebri with complete agenesis of the corpus callosum and bilateral parasagittal pachygyria-polymicrogyria secondary to chronic ischemia.

The article which was recently published contained error. Fig. 1 was incorrectly processed as Fig.

Congenital pial AVF along the falx cerebri with complete agenesis of the corpus callosum and bilateral parasagittal pachygyria-polymicrogyria secondary to chronic ischemia.

Objective: Pial arteriovenous fistula (AVF) is an extremely rare entity due to direct arterial connection with the venous plexus without an intervening capillary network. The objective of this article is to describe a unique case of congenital pial AVF along the interhemispheric falx with complete callosal agenesis and malformation of cortical development within the bilateral anterior cerebral artery territories. We also demonstrated the distinctive feature of temporal stability of the extensive intracranial abnormalities without active intervention.

Sequelae of bilateral luxatio erecta in the acute post-reduction period demonstrated by MRI: a case report and literature review.

Luxatio erecta humeri (LEH), also known as inferior shoulder dislocation, is uncommon, comprising about 0.5% of all cases of shoulder dislocation. Synchronous bilateral LEH is exceedingly rare and, to our knowledge, there are no descriptions of axillary nerve injury on magnetic resonance imaging (MRI) following LEH.

Impulsive-compulsive behaviors are common in Asian Parkinson's disease patients: assessment using the QUIP.

Background: There are limited data on the prevalence of impulsive-compulsive behaviors and subsyndromal impulsive-compulsive behaviors in Asian patients with Parkinson's disease, who are treated with lower dosages of dopaminergic medications.

Methods: The recently-validated Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease was administered to 200 consecutive patients attending a Malaysian university-based neurology clinic. Informant report was also systematically obtained.
