MR-guided focused ultrasound. Current and future applications.

[MR-guided focused ultrasound. Current and future applications]. Radiologe. 2013 Mar;53(3):200-8 Authors: Trumm CG, Napoli A, Peller M, Clevert DA, Stahl R, Reiser M, Matzko M Abstract STANDARD RADIOLOGICAL METHODS: High-intensity focused ultrasound (synonyms FUS and HIFU) under magnetic resonance imaging (MRI) guidance (synonyms MRgFUS and MR-HIFU) is a completely non-invasive technology for accurate thermal ablation of a target tissue while neighboring tissues and organs are preserved. METHODICAL INNOVATIONS: The combination of FUS with MRI for planning, (near) real-time monitoring and outcome assessment of treatment markedly enhances the safety of the procedure. ACHIEVEMENTS: The MRgFUS procedure is clinically established in particular for the treatment of symptomatic uterine fibroids, followed by palliative ablation of painful bone metastases. Furthermore, promising results have been shown for the treatment of adenomyosis, malignant tumors of the prostate, breast and liver and for various intracranial applications, such as thermal ablation of brain tumors, functional neurosurgery and transient disruption of the blood-brain barrier.

ConclusionsOur data suggest that the investigated brain tumors had an intact BBTB, which is impermeable to anticancer drugs, which are dual ABCB1/ABCG2 substrates. Therefore, effective drugs for antitumor treatment should have high passive permeability and lack ABCB1/ABCG2 substrate affinity.Trial registrationEuropean Union Drug Regulating Authorities Clinical Trials Database (EUDRACT), 2011-004189-13.

Out of all types of cancer, brain cancer has the lowest survival rate. Brain tumors can have different types depending on their shape, texture, and location. Proper diagnosis of the tumor type enables the doctor to make the correct treatment choice and help save the patient's life. There is a high need in the Artificial Intelligence field for a Computer Assisted Diagnosis (CAD) syste...

CONCLUSIONS: Future studies will explore potential mechanisms at the brain-tumor barrier to explain lower cyclophosphamide brain penetration in tumor-bearing mice. These results will be used to further investigate exposure-response relationships in medulloblastoma xenograft models. PMID: 31815662 [PubMed - in process]

Shah Islam Hugh Harvey By HUGH HARVEY, MBBS and SHAH ISLAM, MBBS AI in medical imaging entered the consciousness of radiologists just a few years ago, notably peaking in 2016 when Geoffrey Hinton declared radiologists’ time was up, swiftly followed by the first AI startups booking exhibiting booths at RSNA. Three years on, the sheer number and scale of AI-focussed offerings has gathered significant pace, so much so that this year a decision was made by the RSNA organising committee to move the ever-growing AI showcase to a new space located in the lower level of the North Hall. In some ways it made sense to ...

AbstractLaser interstitial thermal therapy (LITT) is an emerging modality to treat benign and malignant brain lesions. LITT is a minimally invasive method to ablate tissue using laser‐induced tissue heating and serves as both a diagnostic and therapeutic modality for progressive brain lesions. We completed a single‐center retrospective analysis of all patients with progressive brain lesions treated with LITT since its introduction at our center in August of 2015. Twelve patients have been treated for a total of 13 procedures, of which 10 patients had brain metastases and 2 patients had primary malignant gliomas. Biopsi...

Conclusion.We suggest that gliomas with astroblastic features include a variety of molecularly sharply defined entities. Adult ABM harboring molecular features of PXA and HGG should be reclassified. Central nervous system high‐grade neuroepithelial tumors with MN1 alterations and histology of ABM appear to be uncommon in adults. Astroblastic morphology in adults should thus prompt thorough molecular investigation aiming at a clear histomolecular diagnosis and identifying actionable drug targets, especially in the mitogen‐activated protein kinase pathway.Implications for Practice.Astroblastoma (ABM) remains a poorly def...

We present a contemporary analysis of risk of fatal stroke among more than 7.5 million cancer patients and report that stroke risk varies as a function of disease site, age, gender, marital status, and time after diagnosis. The risk of stroke among cancer patients is two times that of the general population and rises with longer follow-up time. The relative risk of fatal stroke, versus the general population, is highest in those with cancers of the brain and gastrointestinal tract. The plurality of strokes occurs in patients older than 40 years of age with cancers of the prostate, breast, and colorectum. Patients of any ag...

This study is to investigate the mechanism through which DMBT1 exerts its effects on AR progression. METHOD: DMBT1 levels in the nasal lavage (NL) fluid and the nasal mucosa in AR and control groups were determined by ELISA and IHC. Next, mice were sensitized with ovalbumin; intranasal administrations of recombinant DMBT1 were then performed. DMBT1 in the nasal mucosa of mice were determined by IHC and WB. Nasal symptoms were estimated. IL-4 and IL-5 in BAL fluid and eosinophils infiltration in the nasal cavity were measured through ELISA and HE staining, respectively. RESULTS: DMBT1 levels were found to be signi...
