Review of liver biopsies at Red Cross War Memorial Children's Hospital over a six-year period
… biopsies were performed percutaneously under ultrasound guidance (n=45, 65%). There were three (4.3%) major complications, and no minor complication. The tissue yield was 95.7% (n = 66), with histopathological findings guiding clinical management in 50 patients (72%). Most frequent diagnoses …

Ipsilateral and concurrent breast cancer and atypical ductal hyperplasia: Does atypia also need surgical excision?
… of ipsilateral DCIS over IBC (p=0.034), using ultrasound guidance for biopsy of ADH (p=0.019), and the presence of cell necrosis in the ADH (p=0.039). Neither the radiographic size of the ADH nor the distance of the ADH from the ipsilateral cancer were associated with upgrade. The group at …

Shear-wave imaging guidance for high-intensity focused ultrasound therapy
High-intensity focused ultrasound (HIFU) has attracted many research interests during the last three decades (since 1980s) for the precision of this treatment in the field of medical oncology and brain surgery. Even though the precision of HIFU application/exposure is particularly high, the overall …

Single Crystal Based Ultrasound Actuated Needle For Regional Anaesthesia and Biopsy
Ultrasound guidance of needle-based regional anaesthesia and tissue biopsy is widely used in clinical practice. Ultrasound imaging has improved the efficacy and reduced some side effects during regional nerve block. However, the presentation and interpretation of real-time ultrasound guided needle …

Determining the Oncological and Immunological Effects of Histotripsy for Tumor Ablation
… (NCT04573881). Histotripsy utilizes focused ultrasound to generate acoustic cavitation within a tumor to mechanically fractionate targeted tissues. While pre-clinical work has demonstrated the feasibility of applying histotripsy to solid tumors including primary liver and renal tumors, there …

Study of damage to peripheral nerves caused by anaesthetic needles during regional anaesthesia
<b>Background</b>: Ultrasound guidance is strongly recommended for the safe conduct of regional anaesthesia procedures. It is safe, now has adequate spatial resolution and provides real time visualization of local anaesthetic spread. However, the risk of nerve trauma still remains. A recent …
