The system utilizes a unique spectrometer, proprietary software, six transmit/receive RF coils (80mm, 100mm, 123mm, 145mm, 160mm, 180mm) and sweet spot imaging which provide excellent SNR and exquisite image quality.

The ONI MSK Extreme® 1.5T/ Optima MR430s can offer patients a comfortable, non-claustrophobic experience due to the open, quiet design.

From image quality to patient comfort the ONI MSK Extreme® 1.5T/ Optima MR430s delivers. It is a powerful solution to perform premium musculoskeletal imaging.

Multiparametric MR Enterography

MR Enterography is commonly requested in many MR suites across the world, and the benefits of this exam are substantial to patients. Patients affected by inflammatory bowel diseases such as Crohn's Disease or ulcerative colitis will often undergo many CT scans in their lifetime. Since these diseases primarily affect people between the ages of 15 to 35, the repeated exposure to ionizing radiation comes at significant risk.

MRI and neurodegenerative diseases.

Introduction 

The MRI is a Sophisticated diagnostic and noninvasive method to extract valuable quantitative and qualitative characteristics that can provide a comprehensive understanding of the mechanisms of brain function.Neurodegeneration is the generic term for the progressive loss of structure or function of neurons, including death of neurons.Many neurodegenerative diseases including Parkinson's, Alzheimer's and Huntington's disease can occur as a result of neurodegenerative processes.As research progresses, many similarities appear which relate these diseases to one another at a subcellular level. Discovering these similarities offers hope for therapeutic progress that could improve the outcome of many diseases.But for better understanding of these processes, the clinical diagnosis and the development of therapy is necessary to display these degenerative changes.In clinically acceptable time (less than one hour)  is possible to study the situation by applying multiparametric MRI (anatomical imaging, DTI, DWI, PWI, fMRI, p1, p2, p2 *) a diagnostic method that provides information functional, biochemical and structural data for the brain. The ultimate goal of this method is the individualized treatment of each incident and the time of treatment to maximize the desired effect and halt disease progression. These techniques are described below and based on the literature are unique and highly effective diagnostic methods to better manage the disease.

 

Η MR / PET στην απεικόνιση του πνεύμονα

Μια πιλοτική μελέτη διεξήχθη από ερευνητές στην Γερμανία και θα δημοσιευθεί στο τέλος Αυγούστου στο περιοδικό Radiology δείχνει ότι η τεχνική MR/PET παρέχει διαγνωστικές εικόνες υψηλής ποιότητας για την εκτίμηση πνευμονικών εξεργασιών με ταυτόχρονη μείωση της δόσης ακτινοβολίας κατά τουλάχιστον 75%.
Η μελέτη αυτή προσφέρει δεδομένα που αποδεικνύουν την κλινική χρησιμότητα της υβριδικής απεικονιστικής μεθόδου MR/PET, καθώς όπως ευρέθη παρατηρήθηκε παρόμοιος χαρακτηρισμός των βλαβών και σταδιοποίηση των καρκινικών όγκων σε επτά από τους δέκα ασθενείς σε σύγκριση την κλασσική PET / CT.
Η MR/PET θα μπορούσε να προσφέρει μια σημαντική εναλλακτική επιλογή για την απεικόνιση του θώρακα, μαζί με μια δραματική μείωση στην έκθεση σε ιονίζουσες ακτινοβολίες από περίπου 28 mSv για την μέση δόση μίας εξέτασης PET / CT σε 7 mSv απεικόνιση με MR/PET για ολόκληρο το σώμα, όπως αναφέρει στην μελέτη η επικεφαλής συγγραφέας δρ  Ν. Schwenzer, από τμήμα την πανεπιστημιακή κλινική ακτινολογίας του πανεπιστημίου Eberhard-Karls University στην Tübingen (Radiology, Vol. 264:2, σελ. 551-558).

Molecular Imaging

Molecular Imaging targets the biochemical changes of diseases, which often occur a long time before the morphological expressions. Early detection of these biochemical changes provides many more choices and chances for therapeutic intervention during the early stages of a disease. This is the type of power that can and will transform daily medical practice from a system that reacts to disease and treats symptoms, often after it is too late for a cure, to one that detects disease at the beginning and treats its root cause. Ultimate goal with molecular imaging is to enable disease detection much earlier than is currently possible, which ultimately will obviate unnecessary surgeries and treatments. If an intervention is necessary nonetheless, molecular imaging may also be of help. E. g. by detecting tumor borders during the procedure. And in the best-case scenario, it will also result in more cost-effective treatments.
Molecular imaging holds the potential of simultaneously being able to locate, diagnose, and treat disease in vivo as well as the ability to depict how well a treatment is working early after therapy onset.

Human birth observed in real-time open magnetic resonance imaging

OBJECTIVE: Knowledge about the mechanism of labor is based on as- sumptions and radiographic studies performed decades ago. The goal of this study was to describe the relationship between the fetus and the pelvis as the fetus travels through the birth canal, using an open mag- netic resonance  imaging  (MRI) scanner. 

RESULTS: Delivery occurred  by progressive head extension.  However, extension was a very late movement that was observed when the occiput was in close contact with the inferior margin of the symphysis pubis, occurring simultaneously with gliding downward of the fetal head.
CONCLUSION: This  observational  study  shows,  for  the  first  time, that birth can be analyzed with real-time  MRI. MRI technology allows assessment of maternal and fetal anatomy during labor and delivery. 

Key words:  delivery, imaging, mechanism of labor, magnetic resonance imaging

Η μαγνητική τομογραφία εξηγεί το μύθο του «Homo Economicus»

Η οικονομική κρίση του 2008 φάνηκε να καταρρακώνει για πάντα το μύθο του «Homo Economicus», του ιδανικού ανθρώπινου προτύπου, που αφορά έναν απόλυτα λογικό και εντελώς ιδιοτελή άνθρωπο.
Σημαντική μερίδα επιστημόνων έρχεται τώρα να αμφισβητήσει το δεύτερο σκέλος της ερμηνείας αυτής. Την εναλλακτική θεώρηση προωθεί ο καθηγητής Οικονομικών του Πανεπιστημίου της Βόννης, Αρμιν Φαλκ.

Διαφορετική εγκεφαλική δομή έχουν όσοι έχουν διαπράξει βίαια εγκλήματα

Η εγκεφαλική δομή των πασχόντων από ψυχικά νοσήματα που έχουν διαπράξει βίαια εγκλήματα όπως φόνο και βιασμό, είναι διαφορετική με σαφείς ενδείξεις για δομικές ανωμαλίες, που τους καθιστούν διαφορετικούς από τους άλλους ανθρώπους, σύμφωνα με στοιχεία που δημοσιεύονται στο επιστημονικό έντυπο Archives of General Psychiatry.
