Diabetic Foot Ulcer Imaging: An Overview and Future Directions #C2SHiP #ActAgainstAmputation #Imaging #Diabetes #DiabeticFoot #Diagnostics

This from our combined team from FIU, UCSF, and USC led by Anu Godavarty Diabetic foot ulcers (DFUs) affect one in every three people with diabetes. Imaging plays a vital role in objectively complementing the gold-standard visual yet subjective clinical assessments of DFUs during the wound treatment process. Herein, an overview of the various imaging... Continue Reading →

Combined evaluation of blood flow and tissue perfusion in diabetic feet by intra-arterial dynamic 4DCT imaging #ActAgainstAmputation #DiabeticFoot #Radiology

Fascinating continued work from our Belgian colleagues. Critical limb ischemia is associated with high mortality and major amputations. Intra-arterial digital subtraction angiography (IADSA) has been the reference standard but has some shortcomings including the two-dimensional projection and the lack of tissue perfusion information. The aim of this exploratory study is to examine four-dimensional computed tomography... Continue Reading →

Preliminary evaluation of dual-energy CT to quantitatively assess bone marrow edema in patients with diabetic foot ulcers and suspected osteomyelitis

Preliminary evaluation of dual‐energy CT to quantitatively assess bone marrow edema in patients with diabetic foot ulcers and suspected osteomyelitis Great work as usual from our Dutch compatriots Objectives The purpose of this study is to evaluate the value of dual-energy CT (DECT) with virtual non-calcium (VNCa) in quantitatively assessing the presence of bone marrow...

Simultaneous Segmentation and Classification of Pressure Injury Image Data Using Mask-R-CNN ActAgainstAmputation #DiabeticFoot @ALPSlimb @USC @USC_vascular @ResearchatUSC @KeckSchool_USC #AI #DeepLearning @TheNPIAP

This just published from our SALSA team led by Mark Swerdlow. We're already getting data requests on this one. Building on these models is what it's all about! Mark Swerdlow,1Ozgur Guler,2Raphael Yaakov,2and David G. Armstrong1 Background. Pressure injuries (PIs) impose a substantial burden on patients, caregivers, and healthcare systems, affecting an estimated 3 million Americans and... Continue Reading →

A comprehensive review of methods based on deep learning for diabetes-related foot ulcers #AI #DeepLearning @ALPSlimb #ActAgainstAmputation #C2SHiP

Terrific work from Zhang and coworkers Background: Diabetes mellitus (DM) is a chronic disease with hyperglycemia. If not treated in time, it may lead to lower limb amputation. At the initial stage, the detection of diabetes-related foot ulcer (DFU) is very difficult. Deep learning has demonstrated state-of-the-art performance in various fields and has been used to...

Stratification of Microvascular Disease Severity in the Foot Using Spatial Frequency Domain Imaging

Work from our combined UofA and USC team with our colleagues at Modulim. Samuel Jett 1, Mallory R Thompson 2, Shubhangi Awasthi 2, David J Cuccia 1, Tze-Woei Tan 2, David G Armstrong 3, Amaan Mazhar 1, Craig C Weinkauf 2 Background: Microvascular disease (MVD) describes systemic changes in the small vessels (~100 um diameter) that impair tissue oxygenation and perfusion. MVD is a common but poorly monitored complication of diabetes.... Continue Reading →

SPECT-CT in the early diagnosis of Charcot arthropathy

More strong and practical work from our colleagues at King's... The Role of Bone Scintigraphy with SPECT/CT in the Characterization and Early Diagnosis of Stage 0 Charcot Neuroarthropathy Abstract: We describe the use of Single Photon Emission Computed Tomography/Computed Tomography (SPECT/CT) in the investigation and diagnosis of Charcot neuroarthropathy (CN) in patients with a hot...
