CUBIC UCT held its first Cardiovascular Magnetic Resonance workshop on Friday 5th - Sunday 7th August at Groote Schuur Hospital.

This three day hands-on Cardiovascular Magnetic Resonance Workshop is specifically designed to benefit Radiographers, Radiologists and Cardiologists working on, or interested in MRI, both in a clinical and research environment.

The workshop consisted of a series of lectures, followed by practical sessions based on the theory. During the hands-on sessions, participants had the opportunity to experiment with MRI where they gained a deeper understanding on how to plan, execute and analyse Cardiac MRI scans.

 


A dedicated infant coil was purchased from a University Research Committee equipment grant awarded to Prof Kirsty Donald (PI, Department of Paediatrics) and Prof Ernesta Meintjes.

The coil can be used for high resolution scanning of the head and neck in infants from newborn to 18 months, enabling investigation of early brain development. During the first few months of life many new network connections are being formed, and there is not yet a large influence of confounding environmental factors on brain development.

 


HIV Paediatrics Workshop

Martha Holmes and Frances Robertson attended the 8th International Workshop on HIV Pediatrics in Durban on 15/16 July, where they presented some findings from the neuroimaging substudy of the CHER (Children with HIV Early Antiretroviral) trial. Results from MR spectroscopy show that at age 7 and 9 the children with HIV have higher choline and lower glutamate levels in the frontal gray matter compared to uninfected control children of the same age, in spite of having been on antiretroviral treatment since early infancy.

AIDS Conference

Martha Holmes presented findings from the neuroimaging substudy of the CHER (Children with HIV Early Antiretroviral) trial at the 21st International AIDS conference (AIDS 2016) from 18-22 July. A synopsis of differences found on multimodal neuroimaging between HIV negative children who were born to HIV positive mothers (HIV-exposed, uninfected) and HIV negative children who were born to HIV negative mothers (HIV-unexposed, uninfected), shows that in utero exposure to HIV/ART may affect multiple aspects of brain development.


Sixteen abstracts authored by members of the division of Biomedical Engineering and the department of Psychiatry and Psychology were presented at the 22nd Annual Meeting of the Organization for Human Brain Mapping in Geneva in June. 

These included studies on emotion regulation and functional connectivity in methamphetamine-induced psychosis and fMRI of social cognition subsequent to early childhood trauma; as well investigations into the effects of teratogens and infectious disease on brain structure and function.

An NRF Thuthuka Grant has been awarded to Dr Ali Alhamud for a project entitled "CEST MRI for detecting Glycogen changes (depletion and repletion) pre and post exercise".

The goal of this project is to measure muscle glycogen levels during exercise, and following carbohydrate ingestion after exercise.

To achieve this, we will develop and implement a novel magnetic resonance imaging (MRI) technique called Chemical Exchange Saturation Transfer (CEST) for imaging glycogen levels of tissue.

This technology will be implemented on the full body research-dedicated 3 T Siemens Skyra scanner at the Cape Universities Body Imaging Centre at the University of Cape Town (CUBIC-UCT). 


CUBIC UCT held its first workshop on the Basics of MRI on Friday 27th & Saturday 28th November 2015 at Groote Schuur Hospital.

This two day MRI hands-on workshop was specifically designed to benefit radiographers working on, or interested in, MRI in both a clinical and research environment.

The workshop consisted of a series of lectures, followed by practical sessions based on the theory. During the hands-on sessions, participants had the opportunity to experiment with MRI parameters on the various MRI pulse sequences.

The course content specifically focused on MR safety, components of the scanner, signal creation, image creation, image formation and MR contrast.

Valentine’s Day 2015 marked a historical event as the first research full-body high-field Magnetic Resonance Imaging (MRI) scanner in Africa was delivered to CUBIC-UCT (Cape Universities Body Imaging Centre).

The Siemens Skyra, valued at R24 million, presents the culmination of four years of fundraising by a multi-disciplinary team headed up by Profs Mayosi and Meintjes. Funds were secured from the Technology Innovation Agency, the National Research Foundation, and the Cancer Research Trust. CUBIC, a national imaging facility, is a collaboration between UCT, Stellenbosch University, the MRC and Siemens.

The new site, adjacent to the Psychiatry block at Groote Schuur Hospital, is an extension of the original facility located at Tygerberg Hospital where a brain-only research MRI scanner has been operational since January 2007. This new state-of-the-art machine ushers in a new era of imaging research, including cardiac, abdominal and muscoskeletal.

Shown here to celebrate the arrival of the scanner are (back, left to right) Dr Alhamud, Mrs Samuels, Dr Ntobeko, Prof Douglas, Dr Jankiewicz, Mr Lipsitz, Prof Stein, (front, left to right) Mr Saleh, Mr Denzler, Prof Meintjes.
