2. Detailed Curriculum Breakdown
Semester 1: Advanced Computed Tomography (CT) Systems
- CT Instrumentation & Physics: Helical/spiral geometry, multi-detector row CT (MDCT), slip-ring technology, flat-panel volumetric CT, and detector materials (scintillation crystals with silicon photodiodes).
- Scan Parameters & Optimization: Tube current modulation (organ-based dose reduction), pitch factor selection, matrix sizing, slice collimation, and windowing settings (WW/WL).
- Clinical CT Protocols: High-resolution CT (HRCT) chest, multiphase abdominal imaging (triphasic liver, pancreatic protocol, renal mass staging), CT enterography, trauma whole-body pan-scan, and non-contrast emergency brain triage.
- CT Angiography & Interventional Guidance: Bolus tracking vs. test bolus techniques, timing bolus optimization for carotid, cerebral, pulmonary, and peripheral runoff CTA; CT-guided stereotactic biopsies and drainage procedures.
- Radiation Dosimetry in CT: Computed Tomography Dose Index ($\text{CTDI}_{\text{vol}}$), Dose Length Product (DLP), Effective Dose estimation, and diagnostic reference levels (DRLs).
Semester 2: Magnetic Resonance Imaging (MRI) & Post-Processing
- MRI Hardware & Physical Principles: Superconducting magnet design, passive/active shimming, gradient systems (amplitude, slew rate, rise time), multi-channel phased-array surface coils, and Larmor equation mechanics.
- Pulse Sequence Design & Optimization: Spin Echo (SE), Fast Spin Echo (FSE/TSE), Gradient Echo (GRE), Inversion Recovery (STIR, FLAIR), Chemical Shift imaging (fat suppression techniques), and Fast/Echo Planar Imaging (EPI).
- Advanced Clinical MRI Protocols:
- Neuro: Diffusion-Weighted Imaging (DWI), Perfusion-Weighted Imaging (PWI), Magnetic Resonance Angiography (Time-of-Flight MRA, CE-MRA), MR Venography (MRV).
- Musculoskeletal: High-resolution joint imaging (shoulder, knee, hip labrum, wrist cartilage mapping).
- Abdomen & Pelvis: Magnetic Resonance Cholangiopancreatography (MRCP), Dynamic Contrast-Enhanced (DCE) liver imaging, multi-parametric prostate MRI (PI-RADS standard).
- Workstation 3D Post-Processing: Multiplanar Reconstruction (MPR), Maximum Intensity Projection (MIP), Minimum Intensity Projection (MinIP), Volume Rendering Technique (VRT), and vessel tracking algorithms.
- MRI Safety & Contrast Pharmacology: Projectile hazard zones (Zones I–IV), Specific Absorption Rate (SAR) limits, acoustic protection, screening for passive/active implants, gadolinium-based contrast agents (GBCAs), and Nephrogenic Systemic Fibrosis (NSF) risk stratification.
3. Core Technical & Clinical Competencies Acquired
- Setting up, calibrating, and running high-slice CT scanners (32 to 128+ slice platforms) for routine, emergency, and vascular indications.
- Independently operating 1.5T and 3.0T MRI consoles, adjusting sequence parameters (TR, TE, TI, Flip Angle, NEX/NSA) to balance SNR, spatial resolution, and scan time.
- Handling automatic dual-head power injectors for iodinated and gadolinium contrast media administration, including IV cannulation and extravasation management.
- Identifying and rectifying imaging artifacts in CT (motion, beam hardening, metal streak, ring artifacts) and MRI (ghosting, chemical shift, susceptibility, wrap-around/aliasing).
- Managing DICOM routing, 3D post-processing workflows, and integration with Picture Archiving and Communication Systems (PACS).
4. Career Opportunities & Job Roles
