At many institutions, dual-echo conventional spin echo has been replaced by FSE and FLAIR in routine brain imaging. However, some groups still regard conventional spin echo as a valuable pulse sequence for use in clinical practice. At 3.0T, peripheral triggering is useful for suppressing flow artifacts on the T2-weighted images. Consequently, TR depends on the heart rate, and is often longer than optimal value, yielding unwanted hyper-intensity of CSF in PD-weighted images. This work explores methods to reduce CSF intensity in conventional dual spin echo at 3.0T, and thus improve the conspicuity of lesions.
