Deep Learning Based Approaches For Low Cost Defense Detection, Adele J. Noel-Rickert

All NMU Master's Theses

Pulmonary fibrosis is a progressive interstitial lung disease characterized by the accumulation of fibrotic tissue within the lungs, leading to impaired respiratory function and reduced quality of life. Early detection is important for disease management; however, accurate diagnosis often relies on high-resolution computed tomography (CT), which may not be accessible in all clinical settings. Chest radiography provides a lower-cost and widely available imaging modality, but interpretation of chest X-rays for fibrotic disease can be challenging due to subtle radiographic patterns and overlapping anatomical structures. This thesis investigates the use of multimodal deep learning techniques to assist in pul- monary fibrosis …

Multiplanar First-Ray Deformity And Its Impact On Tibial Sesamoid Assessment: A Radiographic Analysis​, Yasim Zafar, Madelaine Adkins, Jessica Sima

School of Podiatric Medicine - Student Research

This study evaluated whether discrepancies in tibial sesamoid position (TSP) between anteroposterior (AP) and sesamoid axial radiographs are associated with first-ray deformity parameters: first metatarsal rotation angle (MRA), sesamoid rotation angle (SRA), intermetatarsal angle (IMA), and hallux valgus angle (HVA). We hypothesized that increased frontal-plane external rotation of the first metatarsal would be the primary contributor to AP–axial TSP mismatch.

This secondary analysis used deidentified radiographs from Shibuya et al. (J Foot Ankle Surg. 2019). Adults aged 18–80 with measurable TSP on both AP and axial views were included; patients with prior foot trauma or osseous surgery were excluded. Only …

Advances in Clinical Medical Research and Healthcare Delivery

Up to 75% of patients with advanced metastatic disease experience excruciating pain that affects their daily life. We elaborate on a case of a 63-year-old male with Stage IV squamous cell lung carcinoma with advanced osseous metastatic lesions who presented with symptoms of ambulatory dysfunction due to a lesion in the right acetabulum. This case report demonstrates how radiofrequency ablation can offer pain relief through meticulous ablation of a metastatic lesion without the necessity and negative side effects of external beam radiation.

Controlled Antibiotic Release From Emulsion-Loaded Alginate And Fibrin Hydrogels Using Ultrasound, Ziba Ghareh Nazi Fam, Asia Winslow, Mario Fabiilli, Sam Varghese, Brian Oeffinger, Flemming Forsberg, Noreen Hickok, Lauren Delaney

Department of Radiology Faculty Papers

Postoperative infections remain a major complication after spinal fusion surgery, often caused by biofilm-forming bacteria that resist short-term antibiotic prophylaxis. Vancomycin (VAN) is sometimes delivered locally during surgery; however, levels diminish rapidly, leaving patients vulnerable to late-onset infections. We developed a composite hydrogel integrating perfluorohexane-based emulsions within alginate or fibrin matrices to enable both sustained and ultrasound-triggered VAN release. Water-in-oil-in-water emulsions were prepared using fluorosurfactant-stabilized perfluorohexane as the volatile oil phase, then embedded in hydrogels and exposed to ultrasound (2.5 MHz, 5.5 MPa peak negative pressure) to initiate acoustic droplet vaporization for triggered release. Drug release was quantified spectrophotometrically and …

Algorithmic Medicine And The Duty To Disclose: Informed Consent Through The Lens Of Radiology, Lee Rodriguez

Michigan Law Review

Informed consent is the law’s mechanism for protecting patient autonomy by requiring disclosure of facts that bear on the decision to accept or refuse care. Artificial intelligence now helps decide what is medically true for patients, yet informed consent law still assumes that diagnostic judgment is rendered by a human mind whose reasoning is at least in principle communicable. Radiology has become the leading setting for this tension. AI systems triage worklists, flag suspected abnormalities, and anchor first-pass impressions in ways that guide radiologists’ attention and, in practice, can coauthor diagnostic conclusions while remaining invisible to patients. When patients are …
