| Gd: Minimising Dose Without Jeopardising Diagnosis | |
| Susie Huang | |
The safety of gadolinium (Gd) continues to be questioned as concerns grow around gadolinium deposition in the brain and body. This lecture examines strategies for minimizing the dose of gadolinium in clinical practice without compromising diagnosis and management. The presentation will provide an overview of current approaches to avoid or decrease the use of gadolinium in the context of the clinical question that is posed. Emerging techniques for minimizing, if not eliminating, gadolinium will be discussed, and an outlook on the future of gadolinium usage in clinical examinations will be provided. |

A novel extremity MRI scanner with a moving magnetic field led to the development of the Magic Angle Directional Imaging (MADI) technique. This technique harnesses the Magic Angle phenomenon, totally rethinking the way we scan and process images in light of the moving magnetic field. The MADI technique provides a non-invasive way to evaluate the underlying collagen fibre structure in the knee. |

The presentation will cover the complex issues or GBCA elimination / dose reduction techniques and off-label applications in clinical pediatric MRI imaging. The Why / When and How of these strategies will be covered based on our experiences gained over 5 years of Gd reduction scanning. Why we implemented our program 5 yrs ago and lessons we have learnt including the optimisation of imaging sequences, timing of post Gd injections. The Off-Label protocols using Hepatocyte contrast ( Primovist/Eovist ), protocols associated with using macrocyclic agents with age restrictions and a brief insight into the use of Ferumoxytol in children

Basal ganglia degeneration is a hallmark of Parkinson’s disease. However, invivo tracking of these structures has not been fully explored longitudinally.This longitudinal study investigates changes in the volume of basal ganglia nuclei in PD over time, with correlation of these changes in measures of cognition and laterality of motor impairment. At cross-section, the PD group exhibited volume changes in the basal ganglia, but no evidence of a relationship with laterality of symptom onset. Over time, the PD group showed accelerated atrophy relative to controls in the thalamus, caudate, and putamen. |

Implementation of Safety Checklist and Protocols for scanning patients with whole body conditional DBS implants | |

||
Implementing protocols for patients with deep brain neurostimulators (DBS) that have whole body conditions can be challenging. To obtain sequences that meet the B1+rms RF deposition requirements may require modifications image quality and coverage. T1 weighted imaging can be achieved utilizing gradient echo pulse sequences, however these do not suffice for T2 weighted imaging. For T2 weighted turbo spin echo sequences multiple paramter changes are made including echo train length, slice thickness and gap, matrix, averages, flip angle and gradient operation modes. The implementation of a checklists assists the technologists in ensure conditions are met, and patient safety is ensured. |

VARPRO is a novel fat water separation sequence that shows promise for myocardial lipid characterisation. Two questions were addressed in this study: 1. Does VARPRO provide the same myocardial fat-fraction result compared to established magnetic resonance spectroscopy (MRS)? 2. Is the myocardial fat-fraction obtained by VARPRO reproducible? The results suggest the two methods are strongly associated but agreed poorly. The VARPRO estimation is proportionally biased, however, the bias can be easily accounted for using a linear equation. The temporal reproducibility of VARPRO is satisfactory. VARPRO could be a potential, alternative modality to MRS in myocardial lipid quantification. |

High resolution susceptibility map-weighted images (SMWI) has recently been developed to improve visualization of the nigrosome-1 region of the substantia nigra (SN) on 3T imaging. SMWI utilizes susceptibility weighting mask derived from quantitative susceptibility mapping (QSM) to enhance the contrast for the SWI magnitude images. In this study, we explore the utility of SMWI to enhance visual identification of the subthalamic nucleus (STN) at 3T, which may be useful to aid in neuro-navigational procedures requiring precise and accurate identification of the STN such as deep brain stimulation (DBS) surgery. |

||
We retrospectively analyzed 1HMRS data from right and left parietal white matter in a study of 2-year-old children, aiming to determine whether there was a difference between right and left hemispheres in metabolite ratios to creatine. We found concentration ratios of NAA and choline to be higher on the left and Glu+Gln higher on the right. Correlation between right and left was highest for myo-inositol (r= 0.81), but fairly low for NAA (r = 0.63) and Glu+Gln (r = 0.42). Consideration should be given to hemisphere selection when planning 1HMRS studies in young children. |

||
We developed the brain phantom for T1-weighted image (T1WI) showing image contrast and construction similar to those of in vivo MRI by using 3D printer. This phantom was produced according to a novel method using a partial volume effect in a slice plane. As our results, we can see that the T1WI of in vivo and the phantom were in very good agreement. Furthermore, the correlation coefficient (R2) between both T1WIs was 0.941 (p < 0.001). Our phantoms might be powerful tools to use for experiments that need ethically unacceptable long scanning or systematic movements. |

We evaluated the perioperative FA change in CSM patients using ZOOM DTI. As a result, the FA value after decompression surgery showed the proper state of the damaged cord and had a significant positive relationship with the patient’s outcome. The postsurgical FA value can become an accurate prognostic factor. Besides, the presurgical FA value did not have any relationships with the patient’s outcome, the reason why that a masking effect as an “Aligned Fibers Effect” due to strongly stenosis even using fine resolution DTI. |
