Magnetic Resonance Imaging of Aortic Aneurysm Instability

Abdominal aortic aneurysm (AAA) is a progressive enlargement of the aorta, the largest blood vessel in the body. It is at risk of bursting when it is usually fatal. Currently the risk of the AAA bursting is estimated from its diameter. In this study, the investigators hope to develop a new type of aneurysm scan involving Magnetic Resonance Imaging (MRI). It is hoped that this scan will be better at determining which AAAs are at risk of bursting and therefore require an operation to prevent this.

AbstractObjective. The availability of magnetic nanoparticles (MNPs) with medical approval for human intervention is fundamental to the clinical translation of magnetic particle imaging (MPI). In this work, we thoroughly evaluate and compare the magnetic properties of an magnetic resonance imaging (MRI) approved tracer to validate its performance for MPI in future human trials. Approach. We analyze whether the recently approved MRI tracer Resotran is suitable for MPI. In addition, we compare Resotran with the previously approved and extensively studied tracer Resovist, with Ferrotran, which is currently in a clinical phase III study, and with the tailored MPI tracer Perimag. Main results. Initial magnetic particle spectroscopy (MPS) measurements indicate that Resotran exhibits performance characteristics akin to Resovist, but below Perimag. We provide data on four different tracers using dynamic light scattering, transmission electron microscopy, vibrating sample magnetometry measurements, MPS to derive hysteresis, point spread functions, and a serial dilution, as well as system matrix based MPI measurements on a preclinical scanner (Bruker 25/20 FF), including reconstructed images. Significance. Numerous approved MNPs used as tracers in MRI lack the necessary magnetic properties essential for robust signal generation in MPI. The process of obtaining medical approval for dedicated MPI tracers optimized for signal performance is an arduous and costly endeavor, often only justifiable for companies with a well-defined clinical business case. Resotran is an approved tracer that has become available in Europe for MRI. In this work, we study the eligibility of Resotran for MPI in an effort to pave the way for human MPI trials.

The Potential of Iron Oxide Nanoparticle-Enhanced MRI at 7 T Compared With 3 T for Detecting Small Suspicious Lymph Nodes in Patients With Prostate Cancer

BackgroundAccurate detection of lymph node (LN) metastases in prostate cancer (PCa) is a challenging but crucial step for disease staging. Ultrasmall superparamagnetic iron oxide (USPIO)–enhanced magnetic resonance imaging (MRI) enables distinction between healthy LNs and nodes suspicious for harboring metastases. When combined with MRI at an ultra-high magnetic field, an unprecedented spatial resolution can be exploited to visualize these LNs.PurposeThe aim of this study was to explore USPIO-enhanced MRI at 7 T in comparison to 3 T for the detection of small suspicious LNs in the same cohort of patients with PCa.Materials and MethodsTwenty PCa patients with high-risk primary or recurrent disease were referred to our hospital for an investigational USPIO-enhanced 3 T MRI examination with ferumoxtran-10. With consent, they underwent a 7 T MRI on the same day. Three-dimensional anatomical and T2*-weighted images of both examinations were evaluated blinded, with an interval, by 2 readers who annotated LNs suspicious for metastases. Number, size, and level of suspicion (LoS) of LNs were paired within patients and compared between field strengths.ResultsAt 7 T, both readers annotated significantly more LNs compared with 3 T (474 and 284 vs 344 and 162), with 116 suspicious LNs on 7 T (range, 1–34 per patient) and 79 suspicious LNs on 3 T (range, 1–14 per patient) in 17 patients. For suspicious LNs, the median short axis diameter was 2.6 mm on 7 T (1.3–9.5 mm) and 2.8 mm for 3 T (1.7–10.4 mm, P = 0.05), with large overlap in short axis of annotated LNs between LoS groups. At 7 T, significantly more suspicious LNs had a short axis <2.5 mm compared with 3 T (44% vs 27%). Magnetic resonance imaging at 7 T provided better image quality and structure delineation and a higher LoS score for suspicious nodes.ConclusionsIn the same cohort of patients with PCa, more and more small LNs were detected on 7 T USPIO-enhanced MRI compared with 3 T MRI. Suspicious LNs are generally very small, and increased nodal size was not a good indication of suspicion for the presence of metastases. The high spatial resolution of USPIO-enhanced MRI at 7 T improves structure delineation and the visibility of very small suspicious LNs, potentially expanding the in vivo detection limits of pelvic LN metastases in PCa patients.

BACKGROUNDPatients with renal impairment cannot undergo angiography because iodine and gadolinium contrast agents are contraindicated. Iron-containing ultrasmall superparamagnetic iron oxide particles, such as ferumoxtran-10, are not contraindicated in these patients. Thus, patients with renal failure can still undergo angiography with ferumoxtran-10.OBJECTIVETo evaluate the visibility of pelvic vessels with magnetic resonance angiography (MRA) using ferumoxtran-10 as contrast agent.DESIGN, SETTING, AND PARTICIPANTSThree hundred and eighty-one patients diagnosed with primary or recurrent prostate cancer underwent pelvic ferumoxtran-10 MRA. Eleven anatomical pelvic-vessel segments per patient were evaluated using qualitative and quantitative criteria for image quality (IQ), vessel visibility (VV), and the contrast-to-noise ratio (CNR).INTERVENTIONFerumoxtran-10-enhaced MRA.OUTCOME MEASUREMENTS AND STATISTICAL ANALYSISIQ, VV, and CNR were assessed on a 5-point scale for each data set/vessel segment (very poor, poor, moderate, good, and excellent).RESULTS AND LIMITATIONSIQ was good to excellent for 98.2% of the data sets and VV was good to excellent for 97.7% of all vessel segments. The mean CNR for all segments was 88.13 (standard deviation 4.22). Contrast bolus imaging cannot be performed with this technique, so it is impossible to visualize the arterial or venous phase separately. The timing of contrast administration is also a limitation, with MRA performed 1 d after contrast infusion.CONCLUSIONSFerumoxtran-10 MRA showed excellent image quality and visibility for pelvic vessels. In addition, the homogeneity of the intraluminal contrast was superior. Patients with preterminal or terminal renal function can benefit from ferumoxtran-10 MRA if visualization of their pelvic vessels is required.PATIENT SUMMARYMagnetic resonance imaging of blood vessels using a contrast agent called ferumoxtran-10 is a promising technique for patients with impaired kidney function, as it provides high-quality visualization of blood vessels in the pelvis.
