Imaging-Guided Regenerative Aesthetics: A Review of PRP, Stem-Cell, and Fat-Derived Therapies in Interventional Radiology
Abstract
A narrative review examining how image-guided techniques, particularly ultrasound, may improve precision, safety and reproducibility in regenerative aesthetic procedures using platelet-rich plasma, stem-cell-derived products and fat-derived grafts.
Regenerative aesthetic medicine increasingly uses biologically derived, minimally invasive therapies aimed at restoring tissue quality and function. Autologous approaches such as platelet-rich plasma, stem-cell-derived products and fat-derived grafts are used for indications including facial rejuvenation, scar treatment and hair restoration. Many procedures are still performed using landmark-based injection techniques, which may lead to variable placement and procedural risk.
Interventional radiology provides image-guided techniques that allow real-time visualisation of vascular structures and soft-tissue planes. The review examines the clinical efficacy, safety, regulatory issues and standardisation of imaging guidance in regenerative aesthetic procedures.
The published abstract describes a structured search of PubMed, Embase and the Cochrane Database covering 2020 to July 2025. The available literature suggests that image-guided delivery can improve procedural accuracy, distribution of grafts within tissues and patient-reported outcomes compared with traditional landmark-based methods. Considerable heterogeneity remains in biologic preparation, outcome assessment and follow-up duration.
Imaging guidance, particularly ultrasound and Doppler, may allow direct visualisation of blood vessels, needle position and tissue planes, helping clinicians reduce the risk of inadvertent intravascular injection and improve placement of biologic materials.
Current evidence supports potential safety and technical advantages from image-guided regenerative interventions, but the literature remains limited by a shortage of high-quality randomised trials and standardised protocols. Further multidisciplinary research is needed to support evidence-based clinical guidelines.

Real-time imaging emphasised for aesthetic applications.
Improved Procedural Accuracy
The review identifies real-time imaging as a means of visualising tissue planes, vascular structures and needle position, thereby improving precision compared with landmark-based injection techniques.
Most Practical Modality
Ultrasound is described as particularly suited to aesthetic practice because it provides real-time dynamic assessment, does not expose patients to ionising radiation and can be used to visualise superficial vascular and soft-tissue anatomy.
Vascular Mapping
Doppler imaging can identify active blood flow and help clinicians locate vascular structures before and during injection, supporting safer delivery in anatomically sensitive regions.
Targeted PRP Delivery
Image guidance may help clinicians deposit PRP within the intended tissue plane, improve consistency of distribution and reduce the likelihood of vascular or nerve injury.
Precise Cellular Placement
Ultrasound and other imaging techniques may improve targeting of cellular suspensions and allow more consistent delivery into intradermal, subcutaneous or deep fascial compartments.
Improved Graft Distribution
Ultrasound guidance may support appropriate harvest-site selection and more accurate graft placement while allowing real-time visualisation of cannula position and tissue response.
Reduced Vascular Risk
The review highlights inadvertent intravascular injection, vascular occlusion, tissue ischaemia, necrosis, vision loss, fat embolism and retinal artery occlusion as important procedural risks that precision-based delivery seeks to reduce.
Heterogeneous Literature
Differences in biologic preparation, treatment technique, imaging modality, outcome measures and follow-up durations limit direct comparison between studies and hinder standardisation.
GRADE Framework
The detailed methodology reports use of the GRADE framework to assess evidence across PRP, stem-cell-based therapies and fat grafting using study design, bias, consistency, directness and precision.
Standardisation Needed
The review calls for multidisciplinary studies, harmonised protocols and stronger regulatory frameworks to support safe, reproducible and evidence-based integration of interventional radiology into regenerative aesthetics.

Narrative Review
The article is explicitly presented in the published PDF as a Review Article and describes itself as a narrative review intended to synthesise and critically analyse current evidence rather than function as an exhaustive systematic review.
PubMed, Embase & Cochrane Library
The detailed methodology reports searches of PubMed, Embase and the Cochrane Library, supplemented by manual review of reference lists for additional relevant publications.
Database Inception to July 2025
The detailed methodology states that the bibliographic databases were searched from inception through July 2025. The abstract separately describes the search period as 2020 to July 2025.
Keywords & MeSH Terms
Search terms included regenerative aesthetics, platelet-rich plasma, PRP, stem cells, adipose-derived stem cells, fat grafting, stromal vascular fraction, ultrasound-guided injections, CT-guided procedures and interventional radiology. Boolean operators AND and OR were used where appropriate.
Human, English-Language Studies
Eligible studies involved human participants, were published in English, assessed PRP, stem-cell therapy or adipose-derived products delivered with imaging guidance, and addressed aesthetic or reconstructive applications such as facial rejuvenation, scar management, alopecia or soft-tissue volumisation.
Non-Relevant & Non-Imaging Studies
The review excluded non-human studies, non-aesthetic applications, conference abstracts without full articles, and regenerative procedures performed without imaging guidance.
Two-Reviewer Screening
Two individuals completed title and abstract screening. Full-text review was undertaken when eligibility could not be determined from the title and abstract, and disagreements were resolved by consensus.
Clinical & Procedural Variables
Extracted information included study design, patient population, biologic preparation, imaging modality, injection technique, clinical indication, outcomes, follow-up duration and complications.
GRADE Framework
Evidence quality for PRP, stem-cell-based therapies and fat grafting was assessed using the GRADE framework, considering study design, risk of bias, consistency, directness and precision of outcome estimates.
Ultrasound, CT, MRI & Fluoroscopy
The article discusses ultrasound as the most practical modality for routine aesthetic use, with CT, MRI and fluoroscopy having more selective roles in deeper, complex or reconstructive applications.
PRP, Stem Cells & Fat-Derived Products
The review focuses on platelet-rich plasma, stem-cell-based approaches including adipose-derived mesenchymal stem cells, and fat-derived therapies including microfat, nanofat and stromal vascular fraction.
Precision-Based Delivery
The review emphasises the potential role of imaging in reducing incorrect tissue placement, uneven distribution, vascular injury and severe complications associated with inadvertent injection into high-risk vascular territories.
Need for Harmonised Standards
The article highlights the absence of a harmonised global regulatory framework for some regenerative aesthetic therapies and calls for collaboration between regulators, professional societies and academic institutions.
Limited Language & Formatting Support
Artificial intelligence tools were used only during early manuscript preparation for limited language checking and formatting support. Scientific content, literature selection, data interpretation and critical analysis were performed by the authors. The final manuscript was comprehensively rewritten, reviewed and approved by the authors.
