AI Article Synopsis
- Presurgical functional MR imaging (fMRI) could potentially replace intraoperative electrocortical stimulation (ES) for mapping language function during surgeries.
- Although fMRI provides useful insights, such as identifying which hemisphere is language-dominant and assessing proximity to language areas,
- it currently has technical and conceptual limitations that make it less reliable than ES for surgical planning.
- Preliminary clinical experiences support the idea that while fMRI is helpful, it shouldn't fully replace traditional methods yet.
Article Abstract
Presurgical functional MR imaging (fMRI) is discussed as a possible replacement of intraoperative electrocortical stimulation (ES) in the mapping of language function. On the basis of a literature study and illustrated by our own preliminary clinical experience, it is concluded that at present fMRI does offer valuable information by identifying the language-dominant hemisphere preoperatively and estimating the distance between the tumour and functional language areas. However, it is not a reliable alternative to ES because of technical and conceptual problems.

Emphysematous polycystic renal infection (EPRI) has a poor prognosis with conservative management, and early surgical nephrectomy has been recommended. However, percutaneous cyst drainage may be a possible treatment option. We experienced 6 patients with autosomal dominant polycystic kidney disease (ADPKD) presenting with EPRI.

Sialolithiasis is a common cause of salivary gland obstruction, leading to symptoms such as pain and swelling. In cases of intraparenchymal submandibular stones and proximal ductal stones larger than 7 mm, interventional sialendoscopy may fail, necessitating sialoadenectomy. As an alternative, intraoral stone extraction can be performed with CT-guided navigation.

Image reconstruction impacts haemodynamic parameters derived from 4D flow magnetic resonance imaging with compressed sensing.

Aims: 4D blood flow measurements by cardiac magnetic resonance imaging (CMR) can be used to simplify blood flow assessment. Compressed sensing (CS) can provide better flow measurements than conventional parallel imaging (PI), but clinical validation is needed. This study aimed to validate stroke volume (SV) measurements by 4D-CS in healthy volunteers and patients while also investigating the influence of the CS image reconstruction parameter on haemodynamic parameters.

Activatable multifunctional nanoparticles present considerable advantages in cancer treatment by integrating both diagnostic and therapeutic functionalities into a single platform. These nanoparticles can be precisely engineered to selectively target cancer cells, thereby reducing the risk of damage to healthy tissues. Once localized at the target site, they can be activated by external stimuli such as light, pH changes, or specific enzymes, enabling precise control over the release of therapeutic agents or the initiation of therapeutic effects.
