Hemodialysis with end-stage renal disease did not raise the risk of intracranial hemorrhage after a head injury
Conclusions: HD +ESRD did not increase the post-HI risk of ICH. Therefore, it may not be necessary to lower the threshold of head CT in HD +ESRD patients.

Hidden cancer rarely causes out-of-the-blue clots in the bloodstream
Blood clots can be lifesavers when they form outside the bloodstream to stop bleeding from an injury. But they can wreak havoc when they form inside the bloodstream. A blood clot in a coronary artery can cause a heart attack. One in the brain can cause a stroke. Blood clots that form in a leg vein cause a problem known as venous thromboembolism, or VTE. If the clot stays in the leg, it can cause swelling or pain. If it breaks away and travels to the lungs, it can cause a potentially deadly pulmonary embolism. In about half of people who develop a VTE, doctors can identify what caused it. Common causes include an injury; su...

On the Opportunities and Challenges in Microwave Medical Sensing and Imaging
Widely used medical imaging systems in clinics currently rely on X-rays, magnetic resonance imaging, ultrasound, computed tomography, and positron emission tomography. The aforementioned technologies provide clinical data with a variety of resolution, implementation cost, and use complexity, where some of them rely on ionizing radiation. Microwave sensing and imaging (MSI) is an alternative method based on nonionizing electromagnetic (EM) signals operating over the frequency range covering hundreds of megahertz to tens of gigahertz. The advantages of using EM signals are low health risk, low cost implementation, low operat...

Tissue-Specific Sparse Deconvolution for Brain CT Perfusion
Cerebral computed tomography perfusion (CTP) imaging has been advocated to detect and characterize the ischemic penumbra, and assess blood-brain barrier permeability with acute stroke or chronic cerebrovascular disease. In cerebral studies, perfusion hymodynamic parameters such as cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) can be computed from the time sequence of enhanced CT images to provide important guidance to clinicians. However, the associated excessive radiation exposure in the repeated scan during CTP examination is raising a great concern due to numerous recent reports from...

Frequency of New Pulmonary Neoplasm Incidentally Detected by Computed Tomography Angiography in Acute Stroke Patients—A Single-Center Study
Incidental findings of suspect lung opacities are common in computed tomography (CT)–based thorax examinations, especially in high-risk patients, such as stroke patients. Screening with CT of the thorax has detected lung cancer in approximately .31%-1.20% of high-risk populations. The aim of the present study was to report the frequency of suspect lung opacities on routine acute stroke imaging.

A potential role of ECG-gated CT for the diagnosis of pulmonary vein thrombus: an illustrative case report
The presence of tumor thrombus in patients with lung cancer confers a risk of stroke and other end-organ ischemic events. This case highlights a potential role for electrocardiogram (ECG)-gated computed tomography (CT) in the diagnosis of this pathologic process. In this case, pulmonary vein thrombus was definitively identified by an ECG-CT following discordant results between CT and transthoracic echocardiogram. In addition, this case demonstrates how management decisions are affected by physician accessibility to and familiarity with specific imaging tests.

Radiation protection issues in dynamic contrast-enhanced (perfusion) computed tomography
Publication date: Available online 20 November 2014 Source:European Journal of Radiology Author(s): Gunnar Brix , Ursula Lechel , Elke Nekolla , Jürgen Griebel , Christoph Becker Dynamic-contrast enhanced (DCE) CT studies are increasingly used in both medical care and clinical trials to improve diagnosis and therapy management of the most common life-threatening diseases: stroke, coronary artery disease and cancer. It is thus the aim of this review to briefly summarize the current knowledge on deterministic and stochastic radiation effects relevant for patient protection, to present the essential concepts for determinin...

A potential role of ECG-Gated CT for the diagnosis of pulmonary vein thrombus; an illustrative case report
The presence of tumor thrombus in patients with lung cancer confers a risk of stroke and other end organ ischemic events. This case highlights a potential role for ECG-Gated Computed Tomography (ECG-CT) in the diagnosis of this pathologic process. In this case pulmonary vein thrombus was definitively identified by an ECG-CT following discordant results between Computed Tomography (CT) and Transthoracic Echocardiogram (TTE). In addition, this case demonstrates how management decisions are affected by physician accessibility to and familiarity with specific imaging tests.

The value of C-reactive protein in emergency medicine
Publication date: 2014 Source:Journal of Acute Disease, Volume 3, Issue 1 Author(s): Yu-Jang Su C-reactive protein (CRP) is a commonly used tool in emergency department (ED), especially in febrile and infectious patients. It was identified in 1930 and was subsequently classified into an “acute phase protein”, an early indicator of infectious or inflammatory situations in the ED, CRP must be a diagnostic reference and no single value can be indicated to rule in or rule out a specific diagnosis or disease. CRP is a comprehensively assisted tool for evaluation and diagnosis of tissue damage (rheumatologic diseases, stro...

Caution urged over CT scan radiation doses
BBC News reports on a sharp rise in the number of CT scans being performed, exposing people to the potential health risks of radiation. However, as The Daily Telegraph says, it is not possible to calculate the cancer risk due to exposure to CT scans because there is a lack of data. These media stories follow the publication of a report by the Committee on Medical Aspects of Radiation in the Environment (COMARE). COMARE has reviewed trends in the use of CT scans in the UK. The review weighs up the risk-benefit balance of using CT scans, and considers ways to obtain the best quality scan image while minimising the necessary...

Lung cancer screening with low-dose CT (LDCT) is ready for prime time in the USA
Commentary on: Humphrey LL, Deffebach M, Pappas M, et al.. Screening for lung cancer with low-dose computed tomography: a systematic review to update the US Preventive Services Task Force recommendation. Ann Intern Med 2013;159:411–20. Context The US Preventative Services Task Force (USPSTF) has published their long-awaited, updated systematic review of low-dose CT (LDCT) screening for lung cancer. Last reviewed in 2004, lung cancer screening has been under intense study worldwide for the past decade. The issue of lung cancer screening is important because lung cancer is the leading cause of cancer mortality in the U...

Multiple Ischemic Strokes Caused by Nonbacterial Thrombotic Endocarditis Because of Gallbladder Cancer: A Case Report
We report a case of a 62-year-old woman with multiple ischemic strokes caused by nonbacterial thrombotic endocarditis (NBTE) because of gallbladder cancer. Transesophageal echocardiography showed NBTE on the mitral valve. The NBTE disappeared with anticoagulation treatment for 2 weeks. Abdominal computed tomography showed a gallbladder tumor that was surgically resected. Histopathologic studies showed poorly differentiated tumor cells and the production of mucin. Trousseau syndrome with gallbladder cancer is very rare. We suggest that the development of NBTE is related to the production of mucin.

Recurrent Ischemic Stroke in a Patient with the Trousseau Syndrome Treated with Dabigatran
A 70-year-old man with multiple ischemic strokes was diagnosed with cardiac embolism and treated with dabigatran. Three months later, he suddenly developed vertigo and vomiting. Magnetic resonance imaging, showed recurrent lesions and blood tests revealed hypercoagulability, hypoproteinemia, and elevated cytokeratin 19 fragments that serve as a tumor marker of lung cancer. Chest computed tomography showed there were small nodules in bilateral lungs and swollen mediastinal lymph nodes. A conclusive diagnosis was impossible because the patient declined invasive procedures. We suspected primary lung cancer and diagnosed conco...
