In particular, a lung mass was misdiagnosed as a cancer by cMRI, while it was shown to be a pulmonary atelectasis on chest CT examination. Discussion cMRI is a highly reproducible tool to assess myocardial morphology as well as global and regional heart function. It also provides relevant information regarding tissue characteristics such as viability, myocardial perfusion, storage diseases, and inflammation.
In cMRI examinations, a careful assessment of noncardiac structures may also detect relevant noncardiac diseases.
Cardiac magnetic resonance imaging
This enables detecting possible IEFs that could be clinically significant or require further diagnostic work-up [ 8 ]. Few studies are reported in literature concerning the prevalence and the nature of IEFs on cMRI; their comparison is difficult because of different study design i.
In our series, IEFs were encountered in The prevalence of IEFs in our study population is slightly higher than that previously observed: about twofold greater than Chan et al. Sohns et al.
According to Klysik et al. Finally, the clinically significant findings need immediate evaluation or treatment and further diagnostic work-up should be mandatory. In our study, we found two cases of aortic coarctation; sequences dedicated cine-MRI type allowed a detailed study of the anomalies Figure 1 ; further CT scan examinations were therefore considered unnecessary.
Vascular abnormalities such as a case of abnormal pulmonary venous return undiagnosed earlier , mild and severe pleural effusions Figure 2 , consolidative pulmonary parenchymal phenomena Figure 3 , and both benign and malignant pulmonary nodules were found Figure 4. Extracardiac mediastinal masses were also revealed with an accurate analysis of the relationship with the cardiac structures and of mediastinal adenopathy.
About this book
A case of Takotsubo cardiomyopathy is noteworthy with an adrenal mass characterized by an intense enhancement at first pass; a pheochromocytoma was confirmed at following histological examination [ 15 , 16 ] Figure 5. Figure 2: Bilateral pleural effusion.
Figure 5: Axial and coronal localizer SSFP, short axis perfusion, and STIR-T2 short axis images showing an adrenal mass compatible with a diagnosis of pheochromocytoma confirmed at histology.
However, the majority of IEFs were less important and were associated with a benign diagnosis. However, a small percentage of these occasional findings actually have a clinical relevance and deserve further diagnostic investigation.
Finally, in all cases of incidental bony lesions, MR with dedicated sequences or bone scintigraphy may improve the characterization of IEFs. It is therefore extremely important that whoever reports cMRI should be able to properly assess normal and abnormal thorax and superior abdominal findings.
IEFs should be searched, for potentially modifying the clinical management of patients with such findings. Conflicts of Interest The authors have no potential conflicts of interest to disclose.

Right: Flow vectors. Children and congenital heart disease[ edit ] Main article: Congenital heart defect Congenital heart defects are the most common type of major birth defect. Accurate diagnosis is essential for the development of appropriate treatment plans.
CMR can provide comprehensive information about the nature of congenital hearts defects in a safe fashion without using x-rays or entering the body.
Cardiac MRI assessment of myocardial perfusion
It is rarely used as the first or sole diagnostic test for congenital heart disease. Rather, it is typically used in concert with other diagnostic techniques.
In general, the clinical reasons for a CMR examination fall into one or more of the following categories: 1 when echocardiography cardiac ultrasound cannot provide sufficient diagnostic information, 2 as an alternative to diagnostic cardiac catheterization which involve risks including x-ray radiation exposure, 3 to obtain diagnostic information for which CMR offers unique advantages such as blood flow measurement or identification of cardiac masses, and 4 when clinical assessment and other diagnostic tests are inconsistent.
Examples of conditions in which CMR is often used include tetralogy of Fallot , transposition of the great arteries , coarctation of the aorta , single ventricle heart disease, abnormalities of the pulmonary veins, atrial septal defect , connective tissue diseases such as Marfan syndrome , vascular rings , abnormal origins of the coronary arteries, and cardiac tumors.
In order to avoid blurry images the child must remain very still during the examination.
Different institutions have different protocols for pediatric CMR, but most children 7 years of age and older can cooperate sufficiently for a good quality examination. Providing an age-appropriate explanation of the procedure to the child in advance will increase the likelihood of a successful study. After proper safety screening, parents can be allowed into the MRI scanner room to help their child complete the examination.
Some centers allow children to listen to music or watch movies through a specialized MRI-compatible audiovisual system to reduce anxiety and improve cooperation. However, the presence of a calm, encouraging, supportive parent generally produces better results in terms of pediatric cooperation than any distraction or entertainment strategy short of sedation.
If the child cannot cooperate sufficiently, sedation with intravenous medications or general anesthesia may be necessary. In very young babies, it may be possible to perform the examination while they are in a natural sleep. New image capture techniques such as 4D flow require a shorter scan and can lead to reduced needs for sedation.

Main article: History of magnetic resonance imaging The phenomenon of nuclear magnetic resonance NMR was first described in molecular beams and bulk matter , work later acknowledged by the award of a joint Nobel prize in Further investigation laid out the principles of relaxation times leading to nuclear spectroscopy.
In , there was the first report of the difference of the relaxation times for water in myocardium and pure water in spin-echo NMR by Hazlewood and Chang.
In , the first simple NMR image was published and the first medical imaging in , entering the clinical arena in the early s.He has been an author on more than articles in international peer-reviewed journals as well as many book chapters, case reports, and articles in national journals. Level 3 requires 50 hours of approved courses, at least studies performed, sitting a written examination and recommendation by a supervisor.
