“…Sarcoidosis is a multisystem inflammatory disorder that may affect a wide range of organ systems, often presenting with vague and difficult to diagnose symptoms. Both PET and MRI are independently useful in the evaluation of cardiac sarcoidosis and simultaneously acquired FDG PET images and dedicated cardiac MRI, including multiplanar delayed postgadolinium enhancement, may serve even more beneficial. Similarly, both PET and MRI have specific roles in the imaging of inflammatory and infectious vasculitis and osteomyelitis, and early reports suggest that co‐registered anatomic and functional information could prove diagnostically useful .…”

Simultaneous positron emission tomography and MRI (PET/MRI) is a technology that combines the anatomic and quantitative strengths of MR imaging with physiologic information obtained from PET. PET and computed tomography (PET/ CT) performed in a single scanning session is an established technology already in widespread and accepted use worldwide. Given the higher cost and complexity of operating and interpreting the studies obtained on a PET/MRI system, there has been question as to which patients would benefit most from imaging with PET/MRI versus PET/CT. In this article, we compare PET/MRI with PET/CT, detail the applications for which PET/MRI has shown promise and discuss impediments to future adoption. It is our hope that future work will prove the benefit of PET/MRI to specific groups of patients, initially those in which PET/CT and MRI are already performed, leveraging simultaneity and allowing for greater degrees of multiparametric evaluation.

“…Image fusion has been investigated and used in clinic of oral and maxillofacial region for decades, 19 and several methods for image fusion from multiimaging modalities have been introduced. [20][21][22] However, only a few reports were published and the usefulness of the fused image for the observation of TMJ still needs further investigation. Based on the fact that few imaging methods could capture a complete structure information, image fusion could be an alternative for this difficulty.…”

objectives: To present a method for image fusion of cone beam CT (CBCT)/CT and MRI and to explore whether the image data sets fused in such a way could aid the detection of temporomandibular joint (TMJ) anatomical structures and lesions. Methods: There were five cases included in this study. One case was space occupying lesion giant cell tumour of tendon sheaths, one case was chronic inflammation in the condyle, one case was articular disc calcification of the bilateral TMJs, and the other two cases were TMJ disorders (anterior disc displacement without reduction). The digital imaging and communications in medicine format data of CT/CBCT and MRI of the cases were collected, and then imported to the Amira visual software where the registration process was conducted. Based on the different scan model, the registration process could be separated into automatic registration of CT/CBCT with quadrature slice MR images and the semi-automatic registration of CT/CBCT with oblique slice MR images by altering the registration parameters. Rigid transform model and the similarity metric of normalization mutual information was used for registration in the present study. Results: The relationship between the soft mass and hard tissue was shown clearly in the fused images when compared to sole observation of CBCT/CT or MR images. The fused images could define the tumour outline and the destructive bone clearly in the same image. The fused results helped the observers to ensure uncertain defects which could not be confirmed only by one image data set. conclusions: The CT/CBCT and MR images could be fused to aid detection of TMJ anatomical structures and related lesions.

“…On CMRI scan, in CS, we can find late gadolinium enhancement (LGE) related to the presence of fibrous granulomatous tissue, areas with an increased signal on T2-weighted sequences consistent with myocardial edema and with hypointensity suggesting fibrosis [10]. Recently, the value of LGE on CMRI, which allows visualization of even minute amounts of myocardial damage, has been emphasized in diagnosing CS, and it might be a promising tool for determining the prognosis of patients with biopsy-proven extracardiac sarcoidosis [1,16].…”

Sarcoidosis is a rare unknown etiology multisystem inflammatory disease in which noncaseating granulomas (a collection of inflammatory cells) forms and growth in various organs, involving predominantly lungs, intrathoracic lymph node, skin, and eyes. Most commonly, affecting patients between 20 and 40 years old of age, although could be observed at any age (female predominance; rare in Asians). The areas of the body usually affected by sarcoidosis are lungs, skin, or lymph nodes; pulmonary and mediastinal involvement is seen in over 90% of patients. Less commonly eyes, liver, heart, and brain are involved. Any organ, however, can be affected. Early diagnosis of sarcoidosis can be difficult due to few signs and symptoms in its early stages, and when disease does occur, it may mimic other pathologies, and it is achieved through chest X-ray, computed tomography (CT)-high resolution CT (HRCT), gallium scans. Fluoro-deoxy glucose-positron emission tomography (FDG-PET) is another useful tool to assess the extent of disease and has a potential to evaluate the clinical management of patients responding or not to the treatment. Imaging gives, moreover, an important contribution to the evaluation of prognosis and follow-up.

Image fusion between 18F-FDG PET and MRI in cardiac sarcoidosis: A case series

Abstract: 18F-FDG PET and MRI image fusion allows clinicians to obtain complete morphofunctional cartography in patients with sarcoidosis. Our data show that 18F-FDG PET/MRI image fusion imaging can be useful in the diagnosis of CS.
