Dermatology A lesion typical of erythema multiforme–EM in which a vesicle is surrounded by an often hemorrhagic maculopapule; EM is often self-limited, of acute onset, resolves in 3-6 wks, and has a cyclical pattern; EM lesions are 'multiform' and include macules, papules, vesicles, bullae Etiology Idiopathic or follow infections, drug therapy or occur in immunocompromised hosts

Multiplanar reformats and 3D renderings of good-quality micro-CT images facilitated localization of the target lesion within nonfixated lung resection specimens.
There were only two study arteries (7.7%, 2/26) in which cone-beam CT did not allow for the determination of the feeding vessel due to the failure in confirming the relationship between the target lesion and the perfused territory.
Following the second retraction, the guidewire moved forward to enter the target lesion (refer to the Supplemental Video (available here)).
Immediately after the injection of SonoVue, the liver where it was considered to contain the target lesion was scanned with a transducer to detect the arterial enhancement.
These patients had significantly poorer outcomes than those whose treated vessels were at least 2.5 millimeters in diameter, and a sub-analysis excluding these patients showed Absorb BVS to be no longer significantly worse than metal stents at two years in terms of target lesion failure.
This has shown potential utility for target lesions with FDG avidity in biopsy procedures [15].
Additional untargeted, random biopsy cores as well as taking a second targeted biopsy core from the target lesion improved tumor detection rates in our study for both biopsy routes.
Each slice of target lesion was evaluated, the contour of the lesion was delimited avoiding vascular structures of the retroperitoneum, the volume was calculated with volumetric tool, and area of all slices were integrated (Fig.
Patency of the vessel to allow free flow of blood and clinical improvements have increased, and revascularization of the target lesion due to re-closure is low.
In the 12-month follow-up data set, the clinically driven target lesion failure (TLF) rate was 8.9% for patients treated with the Combo Stent, compared to 10.2% for those treated with the TAXUS stent.
In addition, at 3-years, the implantation of a paclitaxel-eluting stent compared to a bare-metal stent resulted in significantly lower rates of ischemia-driven target lesion revascularization (9.4 percent vs.
