Cheat Sheet
- Radiopharmaceutical Decay & Half-Life Calculations -
Mastering the exponential decay formula N=N₀e❻λt (with λ=0.693/t/₂) is essential for arrt nuclear medicine practice exam questions on activity over time. For example, Tc-99m (t/₂=6 h) has λ≈0.115 h❻¹, so only 12.5% remains after 18 h. Try sample calculations like "What fraction remains after three half-lives?" to build confidence.
- Gamma Camera Collimator Types & Selection -
Knowing when to use a parallel-hole, pinhole or fan-beam collimator can boost your score on nuclear medicine imaging techniques quiz items. Use the mnemonic "PAP" (Pinhole for Pediatrics, Parallel-hole for Planar, Fan-beam for Focused regions) to recall applications. Regularly review IAEA guidelines on spatial resolution vs. sensitivity trade-offs.
- Radiation Dose Units & ALARA Principle -
Be fluent in SI units (Becquerel for activity, Gray for absorbed dose, Sievert for dose equivalent) as these appear in nuclear medicine practice questions. Apply ALARA (As Low As Reasonably Achievable) by optimizing time, distance and shielding per SNMMI recommendations. A quick mnemonic: "TDS" (Time ↓, Distance ↑, Shielding ↑) helps cement safety protocols.
- SPECT vs PET Imaging Techniques -
SPECT uses single-photon emitters and mechanical collimation, while PET detects coincident 511 keV annihilation photons, giving higher resolution and sensitivity. In arrt nuclear medicine certification sample questions, note that PET's spatial resolution (~4 mm) surpasses typical SPECT (~8 - 12 mm). Practice comparing clinical applications like myocardial perfusion (SPECT) vs. oncology (PET).
- Quality Control & Equipment Calibration -
Daily QC is vital for reliable images: perform extrinsic and intrinsic flood-field uniformity tests, check energy resolution (should be ≤10% at 140 keV for Tc-99m) and use a Jaszczak phantom for system sensitivity. Follow IAEA Safety Reports and SNMMI practice parameters to schedule weekly, monthly and annual tests. These routines often appear in nuclear medicine radiopharmaceuticals quiz scenarios.
