PET-MRI

PET-MRI combines positron emission tomography (PET) and magnetic resonance imaging (MRI) into one imaging system. Positron emission tomography–magnetic resonance imaging (PET-MRI) is a hybrid imaging technology that incorporates magnetic resonance imaging soft tissue morphological imaging and positron emission tomography functional imaging.

Post-neoadjuvant therapy changes in metabolic metrics from PET/MRI and morphologic metrics from CT were associated with pathologic response and overall survival in patients with pancreatic ductal adenocarcinoma

Pre-treatment (A-C) and post-treatment (D-F) images after eight cycles of systemic FOLFIRINOX and consolidative chemoradiation. Baseline CA 19-9 was 145 U/ml. Pre-treatment whole body axial fused PET/MRI showed FDG avid lesion in body of pancreas (arrow, A) with SUVmax 7.1 and SUVgluc 8.0. Lesion was hypo-enhancing on axial contrast-enhanced T1-weighted (T1W) MR image (arrow, B) from focused abdominal PET/MRI and on CT (arrow, C). Pre-treatment CT tumor volume was 10.3 cm3. Post-treatment whole body axial fused PET/MRI showed complete metabolic response (arrow D) with SUVmax 1.9 and SUVgluc 1.9. Lesion was indistinct on axial contrast-enhanced T1W MRI (arrow, E) and CT (arrow, F), and there was upstream pancreatic parenchymal atrophy. Post-treatment CT tumor volume was 0.46 cm3. There was normalization of CA 19-9. Relative change in SUVmax (ΔSUVgluc) was -73%, and relative change in SUVgluc (ΔSUVgluc) was -76%. Based on change in tumor size, response was categorized as partial response per RECIST. Relative change in tumor volume (ΔTvol) was -96%.

Indeterminate lesion on PET/CT classified by PET/MRI for 53-y-old man with lung cancer.

Indeterminate lesion on PET/CT classified by PET/MRI for 53-y-old man with lung cancer. Contrast-enhanced CT (A), PET (B), and fused 18F-FDG PET/CT (C) images are displayed in comparison with contrast-enhanced T1-weighted MRI (D), PET, and fused 18F-FDG PET/MRI (F) images. In CT (A), hyperdense, subcentimeter liver lesion (arrows) in segment VII is suggestive of transient hepatic attenuation difference or small hemangioma. As malignancy cannot be excluded, it needs further investigation. On PET/MRI, lesion is clearly classified as metastasis because of contrast enhancement and tracer uptake due to later acquisition time point. Follow-up CT confirmed diagnosis after 78 d. Images created by Ole Martin, University Dusseldorf, Medical Faculty and Benedikt Schaarschmidt, University Hospital Essen.

Adult male with decades of right neck pain, discomfort and tightening following birth injury. The patient had failed multiple standard therapeutic maneuvers before presenting for 18F-FDG PET/MR imaging. Images shows abnormally elevated FDG uptake (white arrows; SUVmax = 1.2) observed in a linear pattern in the space in the posterolateral right neck, between the oblique capitis inferior and the semispinalis capitis muscles, where the greater occipital nerve resides. By comparison, the same region on the contralateral, asymptomatic side of the neck has an SUVmax = 0.7. This result encouraged a surgeon to explore the area. The surgeon ultimately found a collection of small arteries wrapped around the nerve in this location. The small arteries underwent lysis by the surgeon and the patient reported tremendous relief of symptoms. (A) Coronal thick slab MIP of 18F-FDG PET.
