      This retrospective study included preoperative MR imaging of 288 pediatric patients with pediatric posterior fossa tumors, including medulloblastoma (n=111), ependymoma (n=70), and pilocytic astrocytoma (n=107). Radiomics features were extracted from T2-weighted images, contrast-enhanced T1-weighted images, and ADC maps. Models generated by standard manual optimization by a machine learning expert were compared with automatic machine learning via the Tree-Based Pipeline Optimization Tool for performance evaluation. The authors conclude that automatic machine learning based on routine MR imaging classified pediatric posterior fossa tumors with high accuracy compared with manual expert pipeline optimization and qualitative expert MR imaging review.

      Intra-Arterial Chemotherapy for Retinoblastoma in Infants ≤10 kg: 74 Treated Eyes with 222 IAC Sessions

      Intra-arterial chemotherapy (IAC) for retinoblastoma (Rb) has dramatically altered the natural history of the disease. Cure rates, globe salvage, and vision preservation have dramatically increased. This retrospective chart review evaluated 207 Rb tumors of 207 eyes in 196 consecutive patients who underwent 658 IAC infusions overall. Patient weights were ≤10 kg in 69 (35.2%) and >10 kg in 127 (64.8%) patients. Comparison (≤10 kg versus >10 kg) revealed that the total number of IAC infusions was 222 versus 436. Periprocedural complications were not significantly different. The authors conclude that intra-arterial chemotherapy in patients weighing ≤10 kg is a safe and effective treatment.

      High Spatiotemporal Resolution 4D Flow MRI of Intracranial Aneurysms at 7T in 10 Minutes  
    	
      L.M. Gottwald, J. Töger, K. Markenroth Bloch, E.S. Peper, B.F. Coolen, G.J. Strijkers, P. van Ooij and A.J. Nederveen

      The authors used pseudospiral Cartesian undersampling with compressed sensing reconstruction to achieve high spatiotemporal resolution (0.5mm isotropic, ∼30 ms) in a scan time of 10 minutes. They analyzed the repeatability of accelerated 4D-flow scans and compared flow rates, stroke volume, and the pulsatility index with 2D-flow and conventional 4D-flow MR imaging in a flow phantom and 15 healthy subjects. Mean flow-rate bias compared with 2D-flow was lower for accelerated than for conventional 4D-flow MR imaging. Pulsatility index bias gave similar results. Stroke volume bias showed no difference from accelerated bias for conventional 4D-flow MR imaging. Repeatability for accelerated 4D-flow was similar to that of 2D-flow MR imaging. They conclude that highly accelerated high-spatiotemporal-resolution 4D-flow MR imaging at 7T in intracranial arteries and aneurysms provides repeatable and accurate quantitative flow values.
