CT study plan

Map every patient-care and safety objective (patient screening and consent, contrast premedication, radiation protection, pregnancy and pediatric precautions) onto a one-page checklist you can recite from memory

Define CT dose descriptors - CTDIvol, CTDIw, DLP, SSDE, effective dose - and state the unit and clinical use of each without notes

Explain how tube current, rotation time, pitch, and kVp each move dose, and predict the direction of change for six worked scenarios

Write a 10-item self-quiz on radiation risk communication and answer it closed-book, scoring yourself

Derive the relationship between pitch, table speed, collimation, and rotation time, then solve eight pitch and dose calculations

Describe x-ray tube construction and the anode-heel, focal-spot, and off-focal radiation effects well enough to explain image consequences

Trace the signal chain from detector through DAS, pre-processing, and reconstruction, naming what each stage changes

List contrast media categories, osmolalities, and the recognition and first-line management of extravasation and anaphylactoid reactions

Compare filtered back projection with iterative and deep-learning reconstruction in terms of noise texture, dose reduction, and artifact behavior

Explain helical interpolation, cone-beam artifacts, and the conditions that force a wider detector or thinner slices

Identify scanner generations and the detector-row geometry that defines slice thickness and z-coverage

Practice selecting collimation, pitch, and reconstruction kernel for four clinical scenarios and justify each choice

Build a protocol summary for head, chest, abdomen-pelvis, and CT angiography covering contrast timing, bolus tracking, and phase delays

Specify oral and IV contrast preparation, timing thresholds, and contraindication screening for each of those protocols

Explain multiphase timing, split-bolus technique, and CT urography sequencing in your own words

Identify the artifacts most likely in each protocol and the patient or equipment cause behind them

Describe CT fluoroscopy, cardiac gating (prospective versus retrospective), and perfusion imaging in terms of acquisition logic and dose trade-offs

Explain window width and level mathematically and predict how changing each alters displayed contrast and noise

Compute and interpret CT numbers for water, air, bone, and contrast, and recognize HU drift from beam hardening

Diagnose ten image-quality problems from written descriptions alone and state the corrective action for each

Apply ALARA and image gently principles to pediatric and bariatric patients by adjusting kVp, mAs, and pitch with stated rationale

Explain quality-control tests for CT number accuracy, uniformity, noise, slice thickness, and spatial resolution, including phantoms and frequency

Describe accreditation and dose-monitoring expectations, including radiation dose index reporting and dose reference levels

Outline patient positioning, immobilization, and shielding decisions that affect both dose and diagnostic quality

Answer 120 mixed-domain practice items under timed conditions and log every error by domain and cause

Re-teach your five weakest concepts aloud or in writing without consulting notes

Recompute dose and pitch problems you previously missed and confirm the method is now automatic

Rank remaining weak areas and assign each a review slot in the final week

Review every item on the week-7 remediation list and close each gap with a written explanation

Rehearse the safety, protocol, physics, and image-evaluation checklists from memory in four short sessions

Complete a second timed set of 60 mixed items and compare accuracy against week 7

Write a one-page personal summary of formulas, protocol thresholds, and safety rules for final review
