Week 4 - Hannah Sheffield

 This week was very productive and busy week. I shadowed Dr. Reichman this week, and saw US guided biopsies, mammographic biopsies, and shadowed diagnostic procedures. I am starting to understand the various ultrasound positions that physicians use to orient themselves. I also learned that suspicious lesions are usually present during digital 2D tomosynthesis, where distortion and MR enhancements show an increased likeliness of a lesion. I also learned about the various views of a mamo, such as CC and MLO for locating calcs. Additionally, when calcs are located in the first few slices of a tomosynthesis, it usually means that it is the skin, and is not suspicious. I also saw some very interesting diagnostic cases.

As for research, I prepared a presentation to give to the Kim Lab group that gave an overview on the on-going work that I have been doing. The presentation was received well, and was given constructive feedback to refine the presentation that I will give at the end of summer immersion. I also ran through all the cases with the working Patlak model, and am still in the process for refining the code for implementing GradNorm to the Patlak model to account for gradient distortions, and a Two-Compartment Model.

Week 3: Eddie Wei - Multimodal Endoscope

Figure 2: Current OCT-Red ( Freund et al.)  and Confocal Fluorescence Microscopy-Green ( Wang et al. ) images in comparison to Histology.           As a brief review of their demonstrated applications in urology, OCT uses backscattered near-infrared light to generate depth-resolved structural images and can delineate bladder layers up to the muscularis with limited cellular information [1], while confocal fluorescence endoscopy uses fluorescein-induced emission and optical sectioning to distinguish...

Week One: Eddie Wei

Over the first week of immersion, I had the opportunity to observe a couple standard urologic operating room procedures, each offering a different perspective on diagnosis, imaging, and operative care. On June 1, I observed two standard operating room procedures. The first involved the treatment of four urinary bladder stones using a cystoscope inserted through the male urethra. The cystoscope was first equipped with a specialized head capable of generating a stream of water to break down the stones. After fragmentation, the water head was replaced with a suction tube to remove the stone fragments and excessive water from the water jet. The procedure was performed under direct real time visualization with a  standard 3x magnification camera integrated into the cystoscope. This procedure lasted 2-3 hours, with 2 and a half hours allocated to breaking down these stones using the water jet.  The second procedure involved a female patient undergoing blue-light cystoscopy to evalua...

Week 1- iqra

This week started off pretty slow since I didn’t meet with my clinician until Wednesday, but things picked up quick ly after that. One thing that has made a big difference is that Dr. Cheung sent an email out to the department about me shadowing, which has allowed me to move around and observe a variety of electrophysiology procedures rather than being limited to a single physician or case type. This has given me exposure to many different aspects of the field and has helped me gain a broader understanding of cardiac electrophysiology. In addition to clinical observations, I also met with one of the medical students working on my research project. During our meeting, we discussed some of the technical details and logistics of the project and worked through a few questions regarding the overall direction of the research. We are still in the early stages of planning, so there are additional details that need to be worked out, and we plan to continue those discussions next week. On Wednes...
