Journal ArticleDOI
Left ventricular diastolic function in type 2 diabetes mellitus: prevalence and association with myocardial and vascular disease.
Mikael Kjær Poulsen,Jan Erik Henriksen,Jordi S. Dahl,Allan Johansen,Oke Gerke,Werner Vach,Torben Haghfelt,Poul Flemming Høilund-Carlsen,Henning Beck-Nielsen,Jacob E. Møller +9 more
TL;DR: Abnormal LV filling is closely associated with abnormal myocardian perfusion on myocardial perfusion scintigraphy, whereas the association of LV filling with vascular function is less prominent.
Journal ArticleDOI
Prospective Comparison of FFR Derived From Coronary CT Angiography With SPECT Perfusion Imaging in Stable Coronary Artery Disease: The ReASSESS Study.
Niels Peter Rønnow Sand,Karsten Tange Veien,Søren Steen Nielsen,Bjarne L. Nørgaard,Pia Veldt Larsen,Allan Johansen,Søren Hess,Lone Deibjerg,Majed Husain,Anders Junker,Kristian Korsgaard Thomsen,Allan Rohold,Lisette Okkels Jensen +12 more
TL;DR: In patients with stable chest pain and CAD as determined by coronary CTA, the overall diagnostic accuracy levels of FFRCT and SPECT were identical in assessing hemodynamically significant stenosis, however, FFR CT demonstrated a significantly higher diagnostic sensitivity than SPECT.
Journal ArticleDOI
Duration of 18F-FDG avidity in lymph nodes after pandemic H1N1v and seasonal influenza vaccination.
TL;DR: Influenza vaccination may lead to FDG-avid draining lymph nodes beyond 1 month, and Chemotherapy or immunosuppressive drugs given within 2 weeks from vaccination did not affect SUVmax in the axillary lymph nodes.
Journal ArticleDOI
Potential impact of myocardial perfusion scintigraphy as gatekeeper for invasive examination and treatment in patients with stable angina pectoris: observational study without post-test referral bias.
Poul Flemming Høilund-Carlsen,Allan Johansen,Henrik Wulff Christensen,Werner Vach,Mette Møldrup,Peter Bartram,Annegrete Veje,Torben Haghfelt +7 more
TL;DR: The use of MPS appears to make about half of catheterizations and almost one-fifth of revascularizations redundant and even in high-risk groups, substantial savings are possible, and the risk of overlooking patients with severe disease seems negligible.
Journal ArticleDOI
FDG PET/CT in cancer: comparison of actual use with literature-based recommendations
Henrik Petersen,Paw Christian Holdgaard,Poul Henning Madsen,Lene Meldgaard Knudsen,Dorte Gad,Anders Eggert Gravergaard,Max Rohde,Christian Godballe,Bodil Elisabeth Engelmann,Karsten Bech,Dorte Teilmann-Jørgensen,Ole Mogensen,Jens Karstoft,Jørgen Johansen,Janne Buck Christensen,Allan Johansen,Poul Flemming Høilund-Carlsen +16 more
TL;DR: The evidence suggested usefulness of PET/CT in lung, lymphoma, melanoma, head and neck, and colorectal cancers, whereas evidence was sparse in gynaecological cancers, and actual use ofPET/CT agreed well with recommendations.
