The Aplio i800 ultrasound scanner from Canon Medical Systems Europe has impressive features, such as Superb Microvascular Imaging (SMI), which can recognize ultra-low-velocity blood flow while keeping a high frame rate and suppressing artifacts and noises. It is an excellent tool that would be useful for several clinical scenarios. Combining SMI with 3D allows a more intuitive rendering of a tumor's vascular network. Here are examples of 2,5 cm ampullary tumors with SMI and SMI in 3D with reconstruction of the vascular tree. We can now achieve these unique images for the first time with EUS.  If you are curious about these new innovative features, please join the Olympus Medical Systems EMEA symposium on Friday, April 26th, during the ESGE Days 2024.  #endoscopy #eus #interventionalendoscopy #3D #medicalimaging #imaging #ultrasound #endoscopic #vascular #canon #olympus #ESGEDays2024 #BRAGE #Haukeland

Deterministic Effects!! * The biological effects, the severity of which depends on the dose received are termed as non -stochastic or deterministic effects. * The deterministic effects exhibit threshold doses, so they can be avoided by limiting the exposure to the levels lower than the threshold doses. * It will appear after some threshold dose, below that it will not come. * Severity increases with dose due to cell killing (severity proportional to dose) * Only can happen in radiation accidents and radiotherapy patients (Acute) * Examples : cataract, infertility, erythema, epilation etc #radiation #effects #deterministic #severity #dose #threshold

Chest radiograph in a 2-year-old child shows a focal contour bulge (arrows) along the left upper cardiac border due to protrusion of the left atrial appendage. Chest radiographic differential diagnosis includes partial pericardial defect, cardiac tumor, and left juxtaposition of the atrial appendages. MRI shows marked dilatation of the left atrial appendage. There is a sharp indentation (arrow) at the junction of the left atrium and appendage (LAA). At operation, the pericardium overlying this region was not deficient but markedly thinned. Diagnosis:Partial eventration of pericardium #cardilogy #pericardium

In this episode, host Dr. Jacob Fleming interviews Dr. Dana Dunleavy about spinal tumor ablation and vertebral augmentation. Dr. Dunleavy is an interventional radiologist and Director of Windsong Interventional & Vascular Services. Dr. Dunleavy delves deeper into the topics of bone tumor ablation and mechanical augmentation. He notes the importance of having a comprehensive understanding of the patient's anatomy and being well-versed in interventional tools. Cement extravasation is a feared complication of vertebral augmentation, so he discusses the role of implants as a means to establish structural support and mitigate the risk of cement leakage. In addition, he talks about his approach in combining ablation with mechanical augmentation so that the augmentation provides a structure after the ablation. Finally, Dr. Dunleavy discusses the use of advanced technology such as cone beam CT in trajectory planning. He shares his hybrid approach to performing bone biopsies, utilizing fluoroscopy during access and cone beam CT to ascertain accurate trajectory.

MULTIMODALITY APPROACH TO A PERIPHERAL PULMONARY NODULE :  THE FIVE STEP APPROACH  Slide 1 This learning case video demonstrates the five step approach which we use to diagnose a peripheral lung nodule A 65 year lady was referred to us for an incidentally picked lung nodule in the right upper lobe 12 mm which was identified during a CT scan performed for evaluation of chronic cough..PET scan did not show any Uptake. As she also had weight loss, it was decided to biopsy the nodule   Step 1 : Identify the lesion on the CT scan and decide on how to biopsy the nodule   Step 2 : Navigating to the nodule. VBN lung point system was used to generate a virtual path. The lesion was adjacent to the bronchus and not within.   Step 3: Radial EBUS was used via a thin bronchoscope and the nodule was identified as an eccentric image. Fluoroscopy was used to confirm the location of probe.  Step 4 : The nodule was biopsied using a 1.1 mm cryoprobe, as the lesion was eccentric and not concentric. Six biopsies were obtained under fluoroscopic guidance.  Step 5 : The biopsy was assessed for adequacy using ROSE, which confirmed the presence of atypical cells. IHC done later confirmed it to be a carcinoid tumor.  Final Dx: PERIPHERAL CARCINOID TUMOR . . #CTScanDiagnosis #LungNodule #MedicalImaging #VBNSystem #NavigationTechniques #Bronchoscopy #RadialEBUSProcedure #FluoroscopyConfirmation #DiagnosticTools #CryoprobeBiopsy #FluoroscopicGuidance #TissueSampling #ROSEevaluation #Immunohistochemistry #drnagarjuna #YashodaHospital #pulmonaryhealth

Chorioangioma of placenta 3D -Hypo- or hyperechoic, well-circumscribed mass -usually located underneath the chorionic plate near the umbilical cord insertion - protrudes into the amniotic cavity. -Color Doppler demonstrates large vascular channels around and within the tumor, feeding vessel can be usually seen -may undergo infarction/resolution with advancing gestation -increase in size may lead to fetal complications(anemia etc) so monitoring is important #drnupurshah #fetalmedicine #chorioangioma
