Cheat Sheet
- T1 Relaxation Fundamentals -
Understand that T1 relaxation time measures longitudinal recovery (Mz) of protons returning to equilibrium after an RF pulse, described by Mz(t)=M0(1−e^(−t/T1)). Remember in the T1 vs T2 weighted MRI quiz that short T1 tissues like fat appear bright due to rapid recovery. A handy mnemonic is "Fat is First" (bright on T1 first).
- T2 Relaxation Fundamentals -
T2 relaxation time tracks transverse decay (Mxy) of protons losing phase coherence, modeled by Mxy(t)=Mxy(0)e^(−t/T2). In T2 weighting, long T2 substances such as CSF glow bright, so water-rich areas stand out. Think "Water Wins" in T2 for quick recall during your MRI sequence quiz.
- Sequence Parameter Tips (TR & TE) -
Short TR (<500 ms) and short TE (<30 ms) favor T1 weighting, while long TR (>2000 ms) and long TE (>80 ms) produce T2 contrast (Radiopaedia, 2023). In the T1 vs T2 weighted MRI quiz, flag these values to determine weighting quickly. You can jot "SSR = short-short = T1, LLC = long-long = T2" as a formulaic aide-mémoire.
- Tissue Contrast Patterns -
Fat appears bright on T1, dark on T2; fluid is dark on T1, bright on T2. This consistent flip-flop pattern underlies many quiz questions on T1 T2 MRI differences. Visualize a "bright fat, bright fluid" road sign toggling between T1 and T2 to cement the concept.
- Clinical Application & Pitfalls -
T1-weighted scans excel at anatomy delineation (e.g., post-contrast lesion detection), whereas T2-weighted images highlight pathology like edema or demyelination (e.g., MS plaques). Beware of CSF flow artifacts in T2 that can mimic pathology - these trap questions often appear in MRI sequence quizzes. Always correlate with clinical context to ace those scenario-based items.
