Audience

Radiology trainees, technologists, radiologists, and multidisciplinary teams seeking quick orientation to advanced imaging capabilities and clinical applications.

FDG PET CT For Oncology Staging And Response Assessment | PET CT Protocols Include Patient Prep (Fasting, Glucose Control), Uptake Time, CT For Attenuation Correction And Diagnostic CT When Indicated

PET MRI Combines Metabolic PET Data With Superior Soft Tissue Contrast Of MRI | Useful In Neurooncology Pediatric Oncology And Selected Body Applications | Longer Acquisition Times And Complex Workflow Require Careful Scheduling

SPECT CT Improves Localization And Attenuation Correction For Bone, Infection, And Endocrine Studies | Use Low Dose CT For Attenuation Correction Or Diagnostic CT When Needed

Standardized Uptake Value (SUV) For Semi Quantitative Assessment | PET Perfusion Tracers And Dynamic Protocols Allow Absolute Myocardial Blood Flow Measurement

MR Spectroscopy For Metabolite Profiling (Brain, Prostate) | fMRI For Functional Mapping Preoperatively | Requires Specialized Sequences And Postprocessing

Diffusion Tensor Imaging For White Matter Tracts | DSC And DCE Perfusion For Tumor Vascularity And Stroke Assessment | Quantitative Maps Require Standardized Acquisition And Postprocessing

Deep Learning Reconstruction And Denoising Algorithms Improve Image Quality At Lower Dose | Validate Algorithms Against Standard Reconstructions And Document Versioning

AI Tools For Lung Nodule Detection Liver Fat Quantification And Cardiac Volumetry Speed Workflow | Always Review Automated Outputs Manually And Record Any Edits

AI Can Prioritize Critical Findings, Auto?populate Measurements, And Assist With Protocol Selection | Ensure Clear Governance, Validation, And Clinician Oversight

Real Time Ultrasound Fused With CT Or MRI Improves Targeting For Biopsy And Ablation | Requires Accurate Registration And Familiarity With Fusion Controls
