In Vivo Quantification of Cerebral R2*-Response to Graded Hyperoxia at 3 Tesla
Conclusions: The GM-R2* responds to hyperoxia in a concentration-dependent manner, suggesting that monitoring and modeling of the R2*-response may provide new oxygenation biomarkers for tumor therapy or assessment of cerebrovascular reactivity in patients.

Energy Limits in Second Generation High-pitch Dual Source CT - Comparison in an Upper Abdominal Phantom
Conclusion: We conclude our study by stating that if there is a need for a higher current, we have to reduce the pitch. In a high-pitch dual source CT, we always have to remember where our main focus is, so we can adjust the pitch to the energy we need in the area of the body that has to be imaged, to find answers to the clinical question being raised.

Noninvasive Fractional Flow Reserve for the Diagnosis of Lesion-specific Ischemia: A Case Example
Jesper Møller Jensen, Lars Christian Gormsen, Henning Mølgaard, Bjarne Linde NørgaardJournal of Clinical Imaging Science 2015 5(1):3-3A physically active 52-year-old male with atypical chest pain was referred to our department. A coronary computed tomography angiography (CCTA) showed a stenotic plaque in the mid left anterior descending coronary artery (LAD). A rest-stress Rubidium-82 myocardial perfusion was normal. One year later the patient sustained a cardiac arrest and percutaneous coronary intervention of the mid-LAD was successfully performed. The original CCTA data were submitted...

Transcatheter Renal Interventions: A Review of Established and Emerging Procedures
Jeet Minocha, Ahmad Parvinian, James T Bui, Martha Grace Knuttinen, Charles E Ray, Ron C GabaJournal of Clinical Imaging Science 2015 5(1):5-5Catheter-based interventions play an important role in the multidisciplinary management of renal pathology. The array of procedures available to interventional radiologists (IRs) includes established techniques such as angioplasty, stenting, embolization, thrombolysis, and thrombectomy for treatment of renovascular disease, as well as embolization of renal neoplasms and emerging therapies such as transcatheter renal artery sympathectomy for treatment of resistant hypertension. Here, ...

Bilateral Renal Lymphangiectasia: Radiological Findings by Ultrasound, Computed Tomography, and Magnetic Resonance Imaging
Khaled Youssef Elbanna, Badr M Almutairi, Ahmed Touni ZidanJournal of Clinical Imaging Science 2015 5(1):6-6Renal lymphangiectasia is a rare benign condition of the kidney without specific clinical presentations. Classic imaging findings are described in literature. Here, we present a case of renal lymphangiectasia with history of bilateral flank pain and abnormal renal function tests. The radiological appearance on ultrasound (US) and computed tomography (CT) showed features of bilateral renal lymphangiectasia but the patient refused invasive procedure for aspiration of the cysts. So, follow-up of the patient was done by ...

Unilateral Agenesis of Internal Carotid Artery with Intercavernous Anastomosis: A Rare Case Report
We present a case of a 25-year-old female with 2-month history of holocranial headache. Neurological examination was unremarkable. Magnetic resonance imaging (MRI) with magnetic resonance angiography (MRA) showed absence of left ICA with an abnormal intercavernous vessel in the sella. Computed tomography (CT) showed absence of the left carotid canal. Doppler ultrasonography (USG) showed high resistance flow in the left common carotid artery (CCA). Since no hemorrhage or aneurysm was seen, patient was managed conservatively and is on regular follow-up. Based on our knowledge, this is the first case to demonstrate the featur...

Transient Rotation of a Non-ptotic Kidney Secondary to Acute Pulmonary Thromboembolism
We present a case of an acquired, transient, rotated right kidney in a 43-year-old woman with an enterocutaneous fistula who presented with acute pulmonary embolism. This non-ptotic rotated kidney returned to its normal orientation within 10 days. We postulate that this transient kidney rotation is due to transient hepatomegaly and passive renal congestion secondary to pulmonary embolism. While in this patient there were no untoward sequelae, it has been reported that ureteral obstruction or vascular occlusion can occur in patients with ptotic and malrotated kidneys, and radiologists, therefore, should be aware of this unu...

Primary Follicular Lymphoma of the Common Bile Duct Mimicking Cholangiocarcinoma
We present a case with history of inflammatory bowel disease and clinical manifestations of obstructive jaundice. Abdominal magnetic resonance imaging with magnetic resonance cholangiopancreatography (MRCP) was done and demonstrated tight stricture at the middle part of common bile duct, and radiological findings were supportive of extra-hepatic cholangiocarcinoma. Whipple's procedure was performed and the case was histopathologically proven to be non-Hodgkin's lymphoma of follicular subtype involving the common bile duct. Lymphoma of the hepatobiliary system is usually present as secondary manifestation of s...

Superior Mesenteric Artery-Related Aortic Pseudomass as a Form of Reverberation Artifact in a 10-Year-Old Boy
We describe an example of a superior mesenteric artery-related pseudomass as a form of reverberation artifact that could lead to misinterpretation of sonographic findings. We present the ultrasonographic and computed tomography angiography findings and give an explanation for the appearance of the artifact. (Source: Journal of Clinical Imaging Science)

Radiography of Cardiac Conduction Devices: A Pictorial Review of Pacemakers and Implantable Cardioverter Defibrillators
Stephanie C Torres-Ayala, Guido Santacana-Laffitte, José MaldonadoJournal of Clinical Imaging Science 2014 4(1):74-74Cardiac conduction devices (CCDs) depend on correct anatomic positioning to function properly. Chest radiography is the preferred imaging modality to evaluate CCD's anatomic location, lead wire integrity, and help in identifying several complications. In this pictorial review, our goal is to familiarize radiologists with CCD implantation techniques, appropriate positioning of the device, common causes of malfunction, methods to improve report accuracy, and assure maximal therapeutic benefi...
