Abstract
Acute ischemic stroke (AIS) afflicts millions of individuals worldwide. Despite the advancements in thrombolysis and thrombectomy facilitating proximal large artery recanalization, the resultant distal hypoperfusion, referred to "no-reflow" phenomenon, often impedes the neurological function restoration in patients. Over half a century of scientific inquiry has validated the existence of cerebral "no-reflow" in both animal models and human subjects. Furthermore, the correlation between "no-reflow" and adverse clinical outcomes underscores the necessity to address this phenomenon as a pivotal strategy for enhancing AIS prognoses. The underlying mechanisms of "no-reflow" are multifaceted, encompassing the formation of microemboli, microvascular compression and contraction. Moreover, a myriad of complex mechanisms warrant further investigation. Insights gleaned from mechanistic exploration have prompted advancements in "no-reflow" treatment, including microthrombosis therapy, which has demonstrated clinical efficacy in improving patient prognoses. The stagnation in current "no-reflow" diagnostic methods imposes limitations on the timely application of combined therapy on "no-reflow" post-recanalization. This narrative review will traverse the historical journey of the "no-reflow" phenomenon, delve into its underpinnings in AIS, and elucidate potential therapeutic and diagnostic strategies. Our aim is to equip readers with a swift comprehension of the "no-reflow" phenomenon and highlight critical points for future research endeavors.

Complete resolution of focal-on-diffuse myocardial activity pattern on FDG PET-CT by prolonging the dietary preparation protocol in cardiac sarcoidosis. J Nucl Cardiol 2023; 30:2525-2530. [PMID: 37524998 DOI: 10.1007/s12350-023-03346-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Accepted: 06/30/2023] [Indexed: 08/02/2023]
Abstract
Patient preparation is crucial for reliable interpretation of cardiac inflammation FDG PET. We share our experience of improved reporting confidence and propose a simple approach of prolonging preparation (from 24 to 48 hours) with the high-fat, no-carbohydrate, and protein-permitted diet followed by fasting in cardiac sarcoidosis in cases with diffuse or focal-on-diffuse myocardial FDG uptake.

Abstract
Zusammenfassung
Hintergrund
Die Myokarditis und die inflammatorische Kardiomyopathie sind aufgrund ihrer unterschiedlichen Auslöser, Phänotypen und Stadien diagnostisch häufig schwer zu diagnostizieren.
Methodische Innovationen und Probleme
Die kardiale Positronen-Emissions-Tomographie/Magnetresonanztomographie (PET/MRT) zeichnet sich neben der myokardialen Gewebecharakterisierung mittels MRT durch den möglichen Nachweis einer aktiven myokardialen Entzündung (Inflammation) mittels PET aus. Die Kombination von MRT und PET ist somit eher synergistisch als rein summativ: Die möglicherweise in der MRT vorhandenen kardialen Veränderungen lassen sich durch die PET in aktive inflammatorische (und somit noch potenziell reversible) Prozesse oder ältere chronische (irreversible) Narben unterscheiden. Die kardiale Sarkoidose mit einem potenziellen Nebeneinander von aktiven und chronischen Veränderungen bietet sich an, um die Stärken einer hybriden PET/MRT zur Geltung bringen zu lassen. Wichtig für eine aussagekräftige kardiale PET ist eine gute Vorbereitung mit Low-Carb-Diät, um eine suffiziente Suppression der myokardialen Glukoseaufnahme zu gewährleisten.
Empfehlungen
Die Diagnostik einer inflammatorischen Herzerkrankung sowie deren Charakterisierung in akut vs. chronische Prozesse gelingt mit der kardialen Hybrid-PET/MRT, wie am Beispiel der kardialen Sarkoidose gezeigt werden konnte.
