Liver examination with MRI has greater diagnostic value than other tests and is one of the more frequent examinations.[1,2] However, the ability to obtain images with good diagnostic value only when the patient breathes constantly.[3] A non-Cartesian Radial method for the collection of K-Space data enables examinations with free breathing differently. 3D VANE XD technique can be applied with mDIXON, a technique with high SNR and excellent fat suppression.[4] Therefore, the difference in Radial percentage, the parameter that most effects motion artifacts in T1 3D VANE XD and 3D-FFE techniques were compared and optimal time versus efficiency value were compared.

Ovarian tumors are multifaceted tumors of the female reproductive system, of which early diagnosis and timely treatment of ovarian tumors is particularly important. In this study, we investigated the efficacy of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), apparent diffusion coefficient (ADC), serum CA125, human epididymal secretory protein (HE4) and their combined application in the differential diagnosis of benign and malignant ovarian tumors and explored the best method to be used in the diagnosis of ovarian tumors.

MRI is recommended by FIGO for staging of cervical cancer, and thus appropriate visualization of the vaginal vault and cervix is important for accurate staging.  MRI has superior soft tissue contrast compared to other imaging modalities.  However, when the vaginal vault is decompressed or the prescription angle is off axis, the utility of MRI becomes limited in evaluating cervical cancer. In this abstract, we explore the use of sterile water-based surgical lubricant as a tool to improve visualization of the cervix and associated structures during MRI.

We offer super rapid phase contrast angiography (PCA) with a 60-second scan. This sequence greatly contributes to managing stroke patients compared with a conventional technique such as time-of-flight MRA. Parallel imaging and optimized voxel size reduce scan time as possible. Tilted optimized non-saturating excitation enhanced the depiction of the distal arteries in transverse acquisition PCA. Super rapid PCA overcomes motion artifacts due to short scan time and the shortest repetition time such as under 7 ms. Moreover, we obtain both MRA and black blood images as a subtraction image between the magnitude image and the MRA image.

This study analyzed the T2* mapping sequence and ventricular function parameters to assess cardiac injury in early cirrhotic cardiomyopathy (CCM) in a rabbit model. At the 2ed week, the ejection fraction (EF) of right ventricle (RV) decreased and the T2* value of 10th segment for LV increased significantly. The liver showed mild iron deposition at the 4th. T2* value of the 10th segment was negatively correlated with that of liver. Suggesting the iron deposition in CCM were not synchronous. Finding the T2* mapping combine right ventricle function for evaluating the occurrence and development of cardiac and liver injury with CCM.

There are two imaging options for nasopharyngeal DWI, one is EPI self-selected echo sequence, and the other is fast spin echo sequence. The two sequences are completely different in the way of reading signals, and each has its own advantages and disadvantages. Traditional EPI imaging has high distortion, and its advantages are fast scanning speed, while TSE sequence has small deformation, but it takes a long time. It takes nearly 4 minutes to scan a complete nasopharynx. In view of the long scanning time and distortion, we put forward two questions. The first question is how to shorten the imaging time while ensuring the image quality; the second question is what is the optimal compression factor for nasopharynx?

Magnetic resonance imaging is continuing to grow for clinical diagnosis in veterinary practice. Although MRI is the gold standard for imaging the central nervous system and musculoskeletal pathology in animals, the use of MRI is limited due to the difficulty in accessing and the higher running cost. It is a limited resource disadvantaging many vet animals and their owners of care and cost. Is it feasible for a human MRI facility to image animals? This paper discusses how this was achieved at the Hunter Medical Research Institute Imaging Centre, Newcastle, Australia, and the safety procedures that were necessary for approval.

Congenitally corrected transposition of the great arteries (ccTGA), is a rare cardiac anomaly (occurring in less than 1% of all congenital heart diseases) characterised by atrio-ventricular and ventricular-arterial discordance. We report on a 13-year-old female with situs inversus totalis, ccTGA, peri-membranous VSD, and sub-PS presenting with worsening fatigue on physical exertion, excessive sweating, and intermittent palpitations not associated with physical activity. Echocardiography was used in diagnosis.    CMR revealed mild systolic impairment (ejection fraction, EF 55%) of the systemic ventricle (morphologic RV), a perimembranous VSD, flattening of the interventricular septum in systole and diastole, indicative of pressure and volume overload, respectively.

Takayasu arteritis (TA) is an uncommon inflammatory disease primarily affecting the aorta and its main branches. It is more common in females (80-90% of cases) and occurs between the ages of 10 and 40 years. We report on a young male patient diagnosed with TA at age 16 years. CMR showed progressive aneurysmal dilatation of the aorta compressing the trachea, left main bronchus, and left lung. Both ventricles showed mild decrease in function (LVEF- 45% and RVEF – 51%). CMR played an important role in disease monitoring and guided patient management.

Colloquially intelligence is correlated to brain size. Although not accurate in humans, is this true in dogs? Dogs are diverse in shapes and sizes and are bred for their unique abilities and behavioural characteristics. However, during clinical MRI examinations, it was clear that although the body mass ranged from approximately 1kg to over 100kg in different breeds, the brain size did not vary drastically. This study will analyse the neurocephalic index of different breeds of dogs to evaluate if this correlates with the dog breeds’ unique abilities.

Intracranial vessel wall (VW) MRI is a state-of-art technology to evaluate vessel wall diseases. It requires high spatial and contrast-to-noise ratio (CNR) resolution as well as capability of blood and cerebrospinal fluid (CSF) suppression to visualize the arterial wall. Our vessel wall protocol including T2 -weighted, 3D time of flight (ToF) MR angiography, diffusion-weighted imaging (DWI), gradient echo imaging (GRE), high resolution post contrast 3D T1-weighted turbo spin echo (TSE) with motion-sensitized driven-equilibrium (MSDE) black blood sequence and post contrast 3D T1-weighted volumetric isotropic fast field echo (FFE) done within 30 minutes which is capable to show vessel wall diseases.

To find out whether this change in position affects the actual fiber tracking, we compared the number of fiber implementations in the median nerve in accordance to neutral and superman position. In 12 of the 14 cases, the superman position produced more fibers than in the neutral position. The reason for this thought is due to the fact that the wrist in the superman position is closer to the isocenter of the magnetic field. Other parameters may be important to optimize the images of wrist DTI, however positioning of the wrist should be considered first.
