Introduction A 55 year old female with a past medical history significant for seizure, spina bifida status post ventriculoperitoneal (VP) shunt, and chronic respiratory failure with chronic tracheostomy on home trilogy ventilator presented with seizurelike activity and dysphagia. Patient was not on any antiepileptic drugs and she did not have seizure for a few years. Electroencephalography revealed no electrographic seizures or interictal epileptiform activity. Head CT showed significant dilatation of the lateral and third ventricles (FIGURES 1 and 2). Further history Xiaoliang (Shawn) Qiu & Fuad M Zeid

Objective: Compared to dynamic contrast enhanced MRI (DCE-MRI), image quality in diffusion-weighted MR imaging (DW-MRI) is generally poor because of low image spatial resolution and distortion. Readout-segmented EPI (RS-EPI) is a recently-developed technique to obtain high resolution DW-MRI with less distortion. The study aimed to evaluate the feasibility of high-resolution DW-MRI of the breast, using RS-EPI and single-shot EPI (SS-EPI). Methods: With IRB approval, 26 patients with clinically suspected breast cancer were prospectively enrolled. Breast MRI was performed on a 3.0 T scanner using a 16-channel breast coil. Sequences include T2-weighted imaging (T2WI) with fat saturation, a 3D DCE-MRI series and DW-MRI (b values of 0 and 850 s/mm2 for RS-EPI and SS-EPI). To evaluate image distortion, the antero-posterior (AP) extent of the mammary gland on DW-MRI with RS-EPI and SS-EPI were measured and differences from values obtained from T2WI were calculated. The artefacts on both sequences were scored. Diagnostic performance of lesions on both sequences was assessed using BI-RADS classification and the category was compared to that determined by DCE-MRI. Results: The average difference in the measured AP extent on DW-MRI with RS-EPI was significantly less than that on DW-MRI with SS-EPI (2.3 ± 2.0 versus 12.5 ± 4.7 mm, respectively, p<0.01). Distortion artefacts were significantly lower on DW-MRI with RS-EPI than that with SS-EPI in all cases. The sensitivity of DW-MRI with RS-EPI was higher than that with SS-EPI (88.9 and 77.8%, respectively). Conclusion: DW-MRI with RS-EPI has an advantage of less distortion compared to that with SS-EPI.
目的:与动态对比增强MRI (DCE-MRI)相比，弥散加权磁共振成像(DW-MRI)的图像质量普遍较差，主要是由于图像空间分辨率低和失真。读数分割EPI (RS-EPI)是近年来发展起来的一种获得低失真高分辨率DW-MRI的技术。本研究旨在评估采用RS-EPI和单次EPI (SS-EPI)对乳房进行高分辨率dw mri的可行性。方法:经IRB批准，前瞻性纳入26例临床疑似乳腺癌患者。在3.0 T扫描仪上使用16通道乳房线圈进行乳房MRI。序列包括脂肪饱和度的t2加权成像(T2WI)， 3D DCE-MRI系列和DW-MRI (RS-EPI和SS-EPI的b值分别为0和850 s/mm2)。为了评估图像失真，我们测量了DW-MRI (RS-EPI和SS-EPI)上乳腺的前后(AP)范围，并计算了与T2WI所得值的差异。对两个序列上的伪影进行评分。使用BI-RADS分类评估两个序列的病变诊断性能，并将分类与DCE-MRI确定的分类进行比较。结果:DW-MRI结合RS-EPI与DW-MRI结合SS-EPI测量AP范围的平均差异显著小于DW-MRI(分别为2.3±2.0 mm与12.5±4.7 mm, p<0.01)。在所有病例中，使用RS-EPI的DW-MRI的畸变伪影明显低于SS-EPI。RS-EPI对DW-MRI的敏感性高于SS-EPI(分别为88.9和77.8%)。结论:与SS-EPI相比，RS-EPI的DW-MRI具有畸变较小的优势。

Introduction The mental foramen (MF) is a topographic anatomical landmark for mental anesthesia in dentistry. It has an oval or circular shape and is located on the outer surface of the mandible on both sides off the midline at a one quarter distance between the profile projections of the mandibular symphysis and posterior edge of the ramus [1]. MF is the output point of the canal of the same name containing a neurovascular bundle.

We analyze the performance of a Weighted Least Squares (WLS) GRAPPA calibration for improving the g-factor of GRAPPA reconstruction from low Signal-to-Noise-Ratio (SNR) acquisition. Our method is particularly useful when the SNR degradation is influenced by noise correlation across channels. When applied with regularization, this form of GRAPPA reconstruction is found to be superior compared to other recent variants of GRAPPA such as coefficient penalized GRAPPA. We demonstrate this feature quantitatively using GRAPPA derived g-factors.

Malignant pleural mesothelioma (MPM) is the most frequent primary neoplasm of the pleura. Although asbestos use has been banned in many developed countries, the incidence has been significantly increasing because of widespread occupational exposure over the last decades. Since the latency between first asbestos exposure and tumor development is around 40 years, the peak age incidence ranges from the sixth to the eighth decades and, since most asbestos exposure is work-related, the incidence is markedly higher in men than in women, the annual rates being 15 cases per million and 3 cases per million, respectively, in the United States. Most commonly, MPM originates within the parietal pleura located in the lower hemithorax and the costophrenic angle. It spreads locally to the ipsilateral visceral pleura and relentlessly invades adjacent structures, such as the lung, chest wall, diaphragm, pericardium, and mediastinum. Disease may invade the contralateral pleural space and the peritoneum. Lymphatic and hematogenous metastases tend to occur late in natural history but are present at autopsy in approximately 50% of patients with MPM. The clinical manifestations are nonspecific and many patients present with advanced-stage disease and comorbidities. The patient prognosis is poor, with a median survival after diagnosis of approximately 12 months. The diagnosis of this neoplasm is often made at a late stage and the prognosis is still very poor with a median survival from diagnosis of under a year with supportive care alone. Achieving early diagnosis and helping to select the most appropriate treatment option in MPM patients is mandatory. In this pictorial essay, the spectrum of imaging features of MPM at Chest Radiography (CXR), Computed Tomography (CT), Magnetic Resonance (MR), Positron Emission Tomography (PET), integrated PET/CT, and Ultrasonography (US) are discussed, and a diagnostic pathway in patients with undiagnosed pleural effusion is proposed.

A coronary artery anomaly is a congenital defect of one or more coronary arteries of the heart in terms of origin, number, course and termination of the artery. A 69 year old lady with angina on exertion admitted to our hospital after detection ischemia of inferior segment of the left ventricle on imaging. Coronary angiography showed an isolated single coronary artery with an aberrant right coronary artery originating from distal left circumflex artery. Here we would like to attract attention to coronary abnormalies by presenting this case.

We propose a novel flow-diverter stent, “valve hybrid fractal stent” to treat the cerebral aneurysm what is one of a cerebrovascular disease. The stent has a valve part to path through a coil. The valve has fractal-pattern structures. So, the blood speed flowing into cerebral aneurysm is reduced. We had experiment of Particle Image Velocimetry (PIV) for evaluation of the inflow of cerebral aneurysm. By the experiment result, we visualized the stream line by using the cerebral aneurysm model. We succeeded in a speed reduction of the inflow with our valve hybrid fractal stent.
