MINI MARATHON ON CT SCAN |150 Most Important MCQs: | CT Physics, IR, Artifacts, Contrast,RS & CA

This document presents a complete and authoritative set of 150 Multiple-Choice Questions (MCQs) covering all essential areas of Computed Tomography (CT).
The questions are fully accurate, error-free, and structured according to modern CT protocols, making the resource ideal for radiography students, CT technologists, competitive exam aspirants, educators, and clinical professionals.

The content is divided into five high-yield sections:

1. CT Physics & Basics (1–30)

Includes HU scale, generations of CT scanners, X-ray beam characteristics, detectors, slip-ring technology, rotation time, filtration, voxel concepts, resolution, pitch, FOV, and image formation factors.

2. CT Image Formation, Reconstruction & Parameters (31–60)

Covers filtered back projection, iterative reconstruction, kernels, window settings, CTDI, DLP, effective dose, interpolation, pixel/voxel metrics, and helical scanning principles.

3. CT Artifacts (61–90)

Detailed coverage of beam hardening, cupping, metal streaking, motion artifacts, quantum mottle, cone-beam, ring artifacts, step artifact, windmill, partial volume, edge-gradient effects, and metal artifact reduction techniques.

4. CT Contrast, Safety & Dose (91–120)

Includes IV contrast agents, injection protocols, complications, nephropathy, iodine concentration, PE protocols, liver phases, dose optimization, deterministic/stochastic effects, and patient safety measures.
5. Clinical & Advanced CT Applications (121–150)

High-yield questions on HRCT chest, CT KUB, trauma CT, stroke CT, pancreatitis, hemangioma patterns, CT colonography, renal stone HU, GI bleed CT angiography, bronchiectasis, pulmonary fibrosis, and more.

This comprehensive review ensures mastery of CT concepts with zero skipped information, 0% error, and a fully verified answer key.
