The metal-chelated 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) has made a significant impact on the field of diagnostic imaging. This imaging mechanism is largely dependent on the four side arm functionalities around the DOTA scaffold. We previously demonstrated the effect of peptoid residue modification on these DOTA side arms, thereby conferring diverse physiochemical properties to the imaging mechanism. Read More

Novel therapeutic options in chronic obstructive pulmonary disease (COPD) require delicate patient selection and thus demand for expert radiologists visually and quantitatively evaluating high-resolution computed tomography (CT) with additional functional acquisitions such as paired inspiratory-expiratory scans or dynamic airway CT. The differentiation between emphysema-dominant and airway-dominant COPD phenotypes by imaging has immediate clinical value for patient management. Assessment of emphysema severity, distribution patterns, and fissure integrity are essential for stratifying patients for different surgical and endoscopic lung volume reduction procedures. Read More

The AGCT is more common type, conversely, less than 5% of tumors are the JGCT and occur in mainly premenarchal girls and in women younger than 30 years. Although JGCT have different histologic features compared to AGCT, the two types have similar imaging features because they have similar gross appearance. Read More

Breast MRI is the most sensitive imaging modality for assessment of the nipple-areola complex (NAC), which is important both in cancer staging and in high-risk screening. However, the normal appearance of the nipple at MRI is not well defined because of a paucity of scientific literature on this topic. Hence, there is a lack of descriptive terminology and diagnostic criteria, which may account for the wide variability in interpretation among radiologists when assessing the NAC on MR images.

Diffeomorphic image registration algorithms are widely used in medical imaging, and require optimization of a high-dimensional nonlinear objective function. The function being optimized has many characteristics that are relevant for optimization but are typically not well understood. Due to that complexity, most authors have used a simple gradient descent, but it is not often discussed how step sizes are chosen or if line searches are used. Read More

Aortic dissection, the rupture of the aorta's intimal and medial layers, leading to the formation of a false lumen, is a relatively common disease with high mortality. So far, while not addressing penetrating aortic ulcer or intramural hematoma, current guidelines take a negative value for d-dimers for a sufficient method to rule out aortic dissection in patients with a low clinical probability, as calculated by the ADD risk score. We present two cases of patients with acute aortic dissection, albeit presenting with a low clinical probability for acute aortic dissection and negative values for d-dimers. Read More

Management of cardiac sarcoidosis (CS) can be challenging. The first-line therapy for this condition is corticosteroids, but other immunosuppressive agents are sometimes co-administered to reduce the dosage of corticosteroid and to thereby avoid steroid-induced adverse effects or to increase its therapeutic efficacy. Mycophenolate mofetil (MMF) is a prodrug of mycophenolic acid, an inhibitor of inosine monophosphate dehydrogenase that acts more selectively on T and B lymphocytes when compared with azathioprine.

Chiari-like malformation (CM) and syringomyelia (SM) is a frequent diagnosis in predisposed brachycephalic toy breeds since increased availability of MRI. However, the relevance of that MRI diagnosis has been questioned as CM, defined as identification of a cerebellar herniation, is ubiquitous in some breeds and SM can be asymptomatic. This article reviews the current knowledge of neuroanatomical changes in symptomatic CM and SM and diagnostic imaging modalities used for the clinical diagnosis of CM-pain or myelopathy related to SM.
