TLDR
Current state-of-the-art pulse sequence technology and its application to the evaluation of ischemic heart disease by means of MR tagging with dobutamine stress testing, MR perfusion imaging, and MR coronary angiography are reviewed.Abstract:
Important advances in rapid magnetic resonance (MR) imaging technology and its application to cardiovascular imaging have been made during the past decade. High-field-strength clinical magnets, high-performance gradient hardware, and ultrafast pulse sequence technology are rapidly making the vision of a comprehensive “one-stop shop” cardiac MR imaging examination a reality. This examination is poised to have a significant effect on the management of coronary artery disease by means of assessment of wall motion with tagging and pharmacologic stress testing, evaluation of the coronary microvasculature with perfusion imaging, and direct visualization of the coronary arteries with MR coronary angiography. This article reviews current state-of-the-art pulse sequence technology and its application to the evaluation of ischemic heart disease by means of MR tagging with dobutamine stress testing, MR perfusion imaging, and MR coronary angiography. Cutting edge areas of research in coil design and exciting new area...read more

Virtopsy, a new imaging horizon in forensic pathology: virtual autopsy by postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI)--a feasibility study
Michael J. Thali,Kathrin Yen,Wolf Schweitzer,Peter Vock,Chris Boesch,Christoph Ozdoba,Gerhard Schroth,Michael Ith,Martin Sonnenschein,Tanja Doernhoefer,Eva Scheurer,Thomas Plattner,Richard Dirnhofer +12 more
TL;DR: Using postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI), 40 forensic cases were examined and findings were verified by subsequent autopsy Results were classified as follows: (I) cause of death, relevant traumatological and pathological findings, (III) vital reactions, (IV) reconstruction of injuries, (V) visualization.

Virtopsy, a New Imaging Horizon in Forensic Pathology: Virtual Autopsy by Postmortem Multislice Computed Tomography (MSCT) and Magnetic Resonance Imaging (MRI) – A Feasibility Study
Michael J. Thali,Kathrin Yen,W Shweitzer,Peter Vock,C Boessh,Christoph Ozdoba,Gerhard Schroth,Michael Ith,Martin Sonnenschein,T Doernhoefer,Eva Scheurer,T Plattener,Richard Dirnhofer +12 more
TL;DR: Preliminary results, based on the concept of "virtopsy," are promising enough to introduce and evaluate these radiological techniques in forensic medicine.

TL;DR: The Gordian knot of anatomy has been the architectural arrangement of ventricular muscle mass, which may have finally become understood and mechanical interactions of structure and function are defined in relation to chronologic location of the successive cardiac functional events in the aortic, left ventricular, and left atrial recordings.

Assessment of Left Ventricular Torsional Deformation by Doppler Tissue Imaging Validation Study With Tagged Magnetic Resonance Imaging
Yuichi Notomi,Randolph M. Setser,Takahiro Shiota,Maureen G. Martin-Miklovic,Joan A. Weaver,Zoran B. Popović,Hirotsugu Yamada,Neil L. Greenberg,Richard D. White,James D. Thomas +9 more
TL;DR: Testing the accuracy of a novel method that uses Doppler tissue imaging (DTI) for quantifying LV torsion in humans with tagged magnetic resonance imaging (MRI) as a reference has shown that DTI can quantifyLV torsional deformation over time.

Computational cardiac atlases: from patient to population and back.
TL;DR: Efficient and robust statistical representations of cardiac morphology and morphodynamics can thereby be obtained, enabling quantitative analysis of images based on such representations, and statistical priors can be used to support cardiac image analysis with applications to advanced quantification and subject‐specific simulations of computational physiology.

Raymond J. Kim,David S. Fieno,Todd B. Parrish,Kathleen E. Harris,Enn-Ling Chen,Orlando P. Simonetti,Jeffrey M. Bundy,J. Paul Finn,Francis J. Klocke,Robert M. Judd +9 more
TL;DR: In the pathophysiologies investigated, contrast MRI distinguishes between reversible and irreversible ischemic injury independent of wall motion and infarct age.

Simultaneous acquisition of spatial harmonics (SMASH): ultra-fast imaging with radiofrequency coil arrays
TL;DR: SiMultaneous Acquisition of Spatial Harmonics (SMASH) as mentioned in this paper is a partially parallel imaging strategy, which is readily integrated with many existing fast imaging sequences, yielding multiplicative time savings without a significant sacrifice in spatial resolution or signal-to-noise ratio.

Multi-planar image formation using nmr spin echoes.
TL;DR: In this paper, a two-dimensional spin density imaging by nuclear magnetic resonance (NMR) is proposed, which exploits the properties of spin echoes in time-dependent magnetic field gradients.

Prognostic Significance of Microvascular Obstruction by Magnetic Resonance Imaging in Patients With Acute Myocardial Infarction
Katherine C. Wu,Elias A. Zerhouni,Robert M. Judd,Carlos H. Lugo-Olivieri,Lili A. Barouch,Steven P. Schulman,Roger S. Blumenthal,Joao A.C. Lima +7 more
TL;DR: After infarction, MRI-determined microvascular obstruction predicts more frequent cardiovascular complications, and infarct size determined by MRI also relates directly to long-term prognosis in patients with acute myocardial infarctions.

Selection of a convolution function for Fourier inversion using gridding (computerised tomography application)
TL;DR: The authors compare the artifact introduced into the image for various convolving functions of different sizes, including the Kaiser-Bessel window and the zero-order prolate spheroidal wave function (PSWF).
