Brief Summary

High field MR-technologies are expected to boost metabolic spectroscopic imaging (MRSI), but also CEST-MRI. This is due to the fact that increased SNR is available which can be used to increase the spatial resolution of all sequences, or reduction of measurement times. Recent findings has shown that MRSI can be used to evaluate the isocitrate dehydrogenase (IDH) status of gliomas, a brain tumor type which is most often diagnosed in humans. Patients with IDH-mutated gliomas have a much longer survival time that IDH-wildtype. In IDH-mutated gliomas the substance 2-hydroxy-glutarate (2HG) is found, whereas in IDH-wildtype gliomas it is not. The underlying trial aims to measure 2HG directly with different MRSI sequences at 3 Tesla (3T) and 7 Tesla (7T) magnetic field strength. Apart from MRSI-techniques for IDH-typing it has been shown that CEST-imaging can also be performed to determine the IDH-status of gliomas. A total of 75 patients and 50 healthy controls will be examined in this study to evaluate the most accurate method for pre-operative IDH-status determination.

Outcome Measures

Primary Outcomes (1)

  • Optimal MR-sequence for IDH-typing

    Finding the most optimal (2HG-edited, radial kspace-sampled) EPSI MRSI/CEST technique for the initial diagnosis of gliomas with respect to IDH-typing. Pre-operative knowledge of the IDH-type is important information for further neurosurgical treatment.

    48 months

Secondary Outcomes (1)

  • Spectral/CEST pattern

    48 months

Study Arms (4)

Sequence optimization (Healthy Control Group 1 (10 Persons))

The MEGA-based editing sequences as well as the SLOW-EPSI sequence will be applied to this group using a 3T Prisma and a 7T Terra scanner. Data will be used for optimization of the pulse sequences. Aim: find those sequence parameters to obtain best spectral quality data (SNR, spatial resolution versus measurement time).

Device: MR-scans using a 3T Prisma and a 7T Terra scanner (Siemens, Erlangen Germany)

Healthy Control Group 2 (15 Persons)

The best performing sequence which will be applied to this group using a 7T Terra scanner. Data will be used normative data for glutamate/glutamine and GABA levels in healthy controls. Aim: normal reference data for future studies.

Device: MR-scans using a 3T Prisma and a 7T Terra scanner (Siemens, Erlangen Germany)

Patient Group 1: Comparison of 5 different spectral editing sequences (30 Patients)

Two editing pulse sequence types will be applied to this group at a 3T Prisma and a 7T Terra scanner. The sequences being compared are MEGA-semiLASER-SVS, MEGA-semiLASER based MRSI (on both 3T and 7T) and SLOW-EPSI (on 7T only).

Device: MR-scans using a 3T Prisma and a 7T Terra scanner (Siemens, Erlangen Germany)

Patient Group 1: Comparison of 4 different CEST sequences (30 Patients)

Two different CEST sequence types will be applied to this group at a 3T Prisma and a 7T Terra scanner. The CEST performance will be compared between 3T and 7T, as well which of the two types in the best on each scanner. Aim: which of the four sequence predicts the IDH-mutation status best.

Device: MR-scans using a 3T Prisma and a 7T Terra scanner (Siemens, Erlangen Germany)

Interventions

The MR-scans performed at 3T and 7T are performed to evaluate whether high field MR-examinations bring an advantage to the patient in determining the IDH-status of the glioma. Two MRSI/CEST sequences will be tested against each other.

Also known as: Examined are fast MRSI sequences and CEST sequences.

Study Population

Healthy controls: Each of the participating healthy adult persons in the study will receive 2 out of 5 different pulse sequences which will be tested against each other (5 groups with 10 healthy controls). In each group two pulse sequences will be tested against each other at 3T and 7T. The data of the healthy controls will be used an normal values to compare patient data against. Patients: 75 patients will be also be split in 5 groups groups of 15 patients. Each patient will receive 2 out of 5 MRSI and/or CEST pulse sequences which will be tested against each other in that group. The best pulse sequence is propagated to the next group. The pulse sequences will be applied at 3T and at 7T (when available). With this approach the researchers hope to find out the most accurate sequence that predicts the IDH-status pre-operatively.
