Interactive protocol optimization webinar on CT Coronary Angiography
Durations: 42:43
About this webinar:
Rapid developments have extended the capabilities of cardiac computed tomography (CT), particularly coronary CT angiography (CTA). However, further parameters are also essential to maximize this essential technology. This webinar discusses the practical application of optimized scanning parameters in coronary CTA, to achieve consistent, low dose, diagnostic imaging. In this interactive webinar, experts from the Maastricht University Medical Centre (MUMC+) will share their experience in coronary CTA protocol optimization and discuss interesting cases. The hosts have been extensively published in high quality journals on this topic including; Investigative Radiology, Euro J Radiol and the Br J Radiol. These scientific principles will underpin the clinical cases that are discussed. During the event, the audience will be encouraged to participate through live polls to share their experiences and challenges, followed by discussion with the panel of experts.

Ultravist® 150, 240, 300, 370 mg I/ml injektions-/infusionsvätska, lösning (Rx V08AB05; EF). Indikationer: Endast avsett för diagnostik. Urografi. Angiografi på såväl artär- som vensida. Digital subtraktionsangiografi. Kontrastförstärkning vid datortomografi. Artrografi. Funktionskontroll av dialysshunt. Dosering: Beror på ålder, vikt, undersökningens art och den använda tekniken. Dosen måste vara så låg som möjligt till patienter som lider av uttalad njurinsufficiens, kardiovaskulär insufficens och till patienter med dåligt allmäntillstånd. Försiktighet bör iakttas hos små barn (under 1 år), som löper större risk för störningar av elektrolybalansen och hemodynamiska obalanser. Äldre: Dosjustering är inte nödvändig. Kontraindikationer: Överkänslighet mot den aktiva substansen eller mot något hjälpämne. Det finns inga absoluta kontraindikationer vid användandet av Ultravist®. Varningar: Mediciner och utrustning för akutbehandling av kontrastmedelsreaktioner skall alltid hållas i beredskap. Hos patienter med dåligt allmäntillstånd bör undersökningsbehovet övervägas extra noggrant. Försiktighet rekommenderas till patienter med lungemfysem eller mångårig diabetes mellitus. Hydrering: Adekvat hydreringsstatus måste garanteras i samband med intravaskulär administrering av Ultravist®. Detta berör särskilt utsatta patienter med exempelvis multipelt myelom, diabetes mellitus, polyuri, oliguri, hyperurikemi samt nyfödda, spädbarn, barn och äldre patienter. Biverkningar: Överkänslighetsreaktioner. Risken för överkänslighetsreaktioner är högre vid tidigare reaktion mot kontrastmedel och tidigare bronkialastma eller andra allergiska åkommor. Allergiliknande reaktioner kan uppträda. De vanligast observerade biverkningarna är huvudvärk, illamående och vasodilatation. De allvarligaste biverkningarna är anafylaktoid chock, andningsuppehåll, bronkospasm, larynxödem, farynxödem, astma, arytmi, hjärtstillestånd och pulmonellt ödem. De flesta av dessa reaktioner uppträder inom 30 minuter efter administrering. Fördröjda reaktioner (efter timmar till dagar) kan uppträda. Störningar i tyreoideafunktionen kan förekomma. Hos neonatala, särskilt för tidigt födda spädbarn, som har blivit exponerade för Ultravist®, antingen via modern under graviditeten eller under den neonatala perioden, bör tyroidfunktionen monitoreras. Akut njurskada (AKI), i form av övergående nedsättning av njurfunktionen kan uppträda efter intravaskulär administrering av Ultravist®. Interaktioner: Biguanider (metformin): Hos patienter med akut njursvikt eller allvarlig kronisk njursjukdom kan eliminationen av biguanid reduceras, vilket leder till ackumulering och utveckling av mjölksyreacidos. Hälso- och sjukvårdspersonal uppmanas att rapportera misstänkt biverkning till Läkemedelsverket. Radioaktiva isotoper: I samband med diagnos och behandling av sjukdomar i tyreoidea med tyreotropiskt radioaktiva isotoper kan upptaget av de radioaktiva isotoperna hämmas i flera veckor efter administrering med Ultravist®. Farmakokinetik: Iopromid distribueras mycket snabbt extracellulärt efter intravaskulär administrering. Plasmaproteinbindningsgraden är ca 1 %. Djurstudier tyder på att iopromid inte passerar en intakt blod-hjärnbarriär, men att en mindre mängd kan passera placenta. Metabolism: Inga metaboliter har påvisats. Vid rekommenderade doser elimineras iopromid nästan uteslutande genom glomerulär filtration. Innehavare av godkännande för försäljning: Bayer AB, Box 606, SE-169 26 Solna. Tlf. +46 8-580 223 00.
