(2026) Urmeneta Ulloa, Javier; Martínez de Vega, Vicente; Molina Borao, Isabel; Álvarez Vázquez, Ana Isabel ; López Alcolea, Julia; Recio Rodríguez, Manuel; Cabrera Rodríguez, José Ángel
This narrative review synthesizes the authors' clinical experience—including practical insights from representative cases from routine practice—with published research to describe the technical foundations, clinical applications, advantages, and limitations of this technique. The study also discusses the technical aspects, including spatial and temporal resolution, velocity encoding, contrast administration, workflow requirements, and post-processing software, and their influence on diagnostic performance.

QR Code–Enabled Self-Access Lifestyle Education in Older People Living With HIV: Pragmatic Pilot Quasi-Experimental Pretest-Posttest Implementation Study
(2026) Jamal-Ismail Ortiz, Yamal; Vico, Santiago; Pérez-Stachowski, Javier; Abilés, Jimena; Alarcón, Pedro; Arenas Villafranca, Javier; Rivas Ruiz, Francisco; Arco, Alfonso Del; Martín Escalante, María Dolores; Et al.
Frailty is prevalent and dynamic in older people living with HIV and is associated with adverse outcomes. Lifestyle support is recommended but difficult to deliver at scale. Digital self-access education may help, although evidence in older, multimorbid populations is limited. This study aims to evaluate 6-month changes in frailty phenotype and related outcomes after a QR code–enabled self-access lifestyle education program on Mediterranean diet and exercise routines for people living with HIV aged ≥60 years.
