The effect of the applied RF field in an NMR experiment on the magnitude of the Spectral Density for a Dipolar Relaxation Mechanism is demonstrated theoretically. The effect is shown with Sin Cos Pulse as a concrete example. The order of magnitude of the magnetic moment where these effects will be significant for typical Rf amplitude values is derived. The effect may be of utility in providing an alternate method of control for MRI Tissue Contrast applications with further development. In contem...

Wünderlich syndrome (WS) is a rare condition, in which spontaneous nontraumatic renal hemorrhage occurs into the subcapsular and perirenal spaces and was described for the first time by Bonet in 1700. The etiology of the entity is very diverse, including benign or malign neoplasms, vascular diseases, infectious and inflammatory kidney diseases, and could be combined with some diseases. Clinically the syndrome is characterized by the classic Lenk's triad. We describe a case of WS in a 37-years-o...

One of the techniques of Nuclear Magnetic Resonance is Diffusion Tensor Imaging, which measures the speed of diffusion of extracellular water molecules found in tissues. Diffusion tensor imaging allows virtual dissections of functional white matter tracts in the human brain in vivo using regions of interest (ROI). The intrinsic trajectories of the olfactory pathway that can be identified using the diffusion- weighted magnetic resonance technique provide an important anatomical reference for the ...

Image quality and accuracy were compared at 120 and 100 kVp tube energies with respect to quantitative image parameters and prediction of surgical findings. Material and methods: A total of 193 patients were reviewed, all of whom underwent laparoscopic donor nephrectomy with preceding CTA evaluation over a 5.5 year period......

The aim of this study was to evaluate radiation protection techniques in computed tomography (CT) scanning, address concerns on the increased population exposure during CT procedures, and provide a review on dose management and optimization procedures. Radiation protection in CT requires regular dose surveys and optimization of CT exposure parameters, establishing and/or implementing diagnostic references (DRLs), implementation of a comprehensive quality assurance program, reference dose levels,...

Objectives: Adult patients with intracranial hemorrhage (ICH) are often young but receive serial cranial computer tomography (CCT). To lower their cumulative radiation dose risks, we evaluated applicability of low dose cranial CT (LD-CCT) in the follow-up of ICH patients compared to an initial standard dose cranial CT (SD-CCT). Methods: 53 ICH patients underwent initial SD-CCT (350 mAs/120 kV) and follow-up LD-CCT (either 220 or 240 mAs/120 kV). Iterative reconstruction used for both dose levels...

The American Lung Association has recently led a national workgroup to develop The National Radon Action Plan: A Strategy for Saving Lives. The U.S. Environmental Protection Agency (EPA) is the lead governmental organization projected to implement this plan. The stated intent of the plan is to address the 'radon problem' in the United States, with the aim of saving 3,200 lives by the year 2020 through preventing at least a portion of the lung cancer mortality that is assumed to arise from inhali...

The addition of thoracic RT to chemotherapy for limited stage small cell lung cancer (LS-SCLC) patients provides improved local control and overall survival. Despite the improved outcomes provided by thoracic RT, LS-SCLC has a high local recurrence rate and low survival after contemporary treatments. Local control rates remain 47% at 2-years, and 5-year overall survival remains 5-10%....

An aberrant internal carotid artery (ICA) in the middle ear is a rare and potentially serious vascular anomaly. Symptoms and signs of aberrant internal carotid artery are often non-specific, therefore radiographic investigation with the combination of CT scan and MRA is required for the diagnosis. It is also essential to inform physicians to avoid disastrous consequences....

Laser effects on fracture healing are still controversial and require further quantitative 3D measures of newly formed bone microstructural parameters. We performed a demonstrative investigation, by synchrotron radiation-based phase-contrast microtomography (SR-phc-microCT), on bone regeneration process in rats submitted to femoral osteotomy and treated with low power laser therapy (LPLT)....

The Effectiveness of lower doses of high-LET radiations is not accurately determined by using energy-based physical parameters such as absorbed dose and radio-sensitivity parameters. Therefore, an attempt has been carried out in this research to propose alternative parameter that capable to quantify the effectiveness of these high LET radiations at lower doses regions. The linear energy transfer and mean free path for linear primary ionization are employed as distinct parameters to achieve this ...

Bowel obstruction resulting from ovarian masses is a serious complication of these diseases. This may be caused by bulky masses filling the pelvis and the abdomen, and should be carefully worked out by pre-operative imaging because of their non-specific clinical signs that may be confused with those due to other conditions such as: volvulus, cancer or adhesions....

Neuroblastoma is one of the most common malignant tumors in children. Its abdominal location is the most met (70%) giving an aspect of abdominal-pelvic mass. It raises a problem of differential diagnosis with wilms tumor with which it does not have the same treatment or the same prognosis. Hence the importance of a positive diagnosis and an accurate staging and monitoring of appropriate treatment for which medical imaging plays a major role. It is represented by plain film of the abdomen, ultras...

This is a case report of an emergency embolization of a left colic aneurysm performed on a 72 year-old woman. The abdominal CTA scan showed a large retroperitoneal hematoma and an aneurysm of a branch of the inferior mesenteric artery. A selective angiography of the inferior mesenteric artery confirmed an aneurysm of the left colic artery. An endovascular ligation was performed with platinum microcoils. The 3-month follow-up confirmed the complete exclusion of the aneurysmatic vessel....

The major site of bronchial hemorrhage in inflammatory hemoptysis is vessel anastomoses (VA) between pulmonary and systemic arteries. Three-dimensional computed tomographic angiography (3D-CT angio) was applied to depict VA for accurate access in endovascular treatment (EVT) for two patients with bronchiectasis. Fusion of the images of pulmonary and systemic 3D-CT angio visualized VA of potential hemorrhagic bronchi. VA depiction allowed successful EVT for hemoptysis with exclusion of non- respo...

Radiofrequency ablation (RFA) is frequently used to treat small hepatocellular carcinoma (HCC), with similar outcome to surgery. The procedure is relatively safe, with low morbidity and mortality rates. The most common major complications are both intra-hepatic (bleeding, abscess and biliary injury) and extra-hepatic (peritoneal bleeding, gastrointestinal perforation, pleural effusion). We report a successfully managed case of spontaneous bacterial peritonitis (SBP) after RFA of a left liver lob...

Lung cancer is the leading cause of cancer death worldwide. Recently, the National Lung Screening Trial (NLST) demonstrated that, relative to chest x-ray, a 20% decrease in mortality was observed for high risk subjects screened with low dose chest CT. Chest CT unavoidably images non-cardiovascular, non-pulmonary organs such as thyroid, adrenals, liver, kidneys and other structures in the upper abdomen. Moreover, when utilizing a low dose screening-chest CT protocol, the images are often noisy an...

Unilateral renal cystic disease (URCD) is a rare entity with few reported cases. This condition is often misdiagnosed for other cystic renal diseases like autosomal dominant polycystic kidney disease, cystic dysplastic kidney disease and cystic nephroma. Nevertheless, this is a benign entity with a potential for good prognosis. Imaging features, supported by background clinical and biochemical findings, diagnosis of URCD is possible. A case of URCD is reported here, having diagnosed on imaging f...
