Fibromuscular dysplasia (FMD) is a rare, non-atherosclerotic vascular disease affecting medium to large arteries, especially the renal and internal carotid arteries (ICAs). The string-of-beads appearance, indicative of alternating areas of stenosis and dilatation, is a key imaging feature typically observed in the distal ICAs. Diagnosing FMD in critically ill patients poses challenges due to the risks associated with traditional imaging methods such as computed tomography angiography (CTA), magnetic resonance angiography, and digital subtraction angiography.

Introduction: Intracranial epidural abscesses require swift diagnosis and treatment. While magnetic resonance imaging (MRI) is preferred for its detailed visualisation, it is costly and time-consuming. Transcranial sonography offers a rapid, portable and cost-effective alternative for assessing brain lesions.

Unlike her typical seizures, the myoclonus exhibited a distinct semiology, involving both positive and negative muscle jerks affecting multiple limb muscles while sparing the face. In addition, neurological examination revealed low-amplitude, arrhythmic movements of the hands and fingers, resembling minipolymyoclonus.

This noninvasive technique demonstrates high sensitivity and specificity in diagnosing various lung pathologies, including pleural effusion and consolidation syndrome. A novel trans-hepatic subcostal approach enhances visualization of the lower right lung lobe, revealing the diaphragm dome and inferior lobe through oblique coronal sections.

Some applications stand to benefit from amplification of the advantageous properties of a NP, but this amplification is not a simple matter of scaling for size-dependent properties. One promising approach to amplification is, therefore, to assemble many copies of a NP into a larger but still nanoscale and colloidal entity.
