Dual steristrip technique: a novel use of steristrips to reduce operator radiation dose during CT-guided intervention

Piggyback Technique-A Safe Way of Performing Rib Biopsy

Rib biopsy can be challenging. A spectrum of bone biopsy techniques are available to undertake Rib Bone biopsy and yield a histological specimen. In this technical report, we described a new Piggyback technique of performing rib biopsy to decrease the incidence of pneumothorax and consolidate diagnostic accuracy.

Current role and future applications of image-guided interventional procedures in musculoskeletal oncology - A narrative review

Background

Musculoskeletal (MSK) image-guided interventional procedures have been increasingly used in and remain crucial in the diagnosis and treatment of musculoskeletal tumours.

Aims

In this article, we aim to describe commonly performed interventional procedures in the subspeciality of MSK oncology drawing experience from our tertiary referral centre. Recent advances, emerging techniques and future applications of image-guided interventional procedures in the field of MSK oncology are highlighted.

Material and methods

A retrospective search using the keyword 'musculoskeletal system', 'neoplasms', 'biopsy', and 'interventional radiology' was performed at our tertiary care oncology orthopaedic referral centre radiology database. The radiology images were collected from our Picture Archiving and Communication System (PACS) and Radiology Information System (RIS). Electronic Patient Records, histopathology laboratory records and patient characteristics were collaborated to generate this narrative experience at our centre.

Results

Image-guided interventional procedures have been utilised in a spectrum of primary and secondary MSK tumours. Current applications include diagnosis of bone and soft tissue MSK neoplastic lesions with biopsies, thermal, cryotherapy and Radiofrequency ablations and augmentation procedures.

Conclusion

Musculoskeletal (MSK) image-guided interventions have increasing applications in the diagnosis, management, treatment and monitoring of patients with MSK tumours. The emergence of newer imaging technologies with enhanced skills of interventional radiologists will allow a range of therapeutic MSK interventions in both effective control of primary lesions and palliative care of metastatic lesions.

Birmingham Intervention Tent Technique (BITT): A Technical Note

Objective We describe a novel and safe CT biopsy technique that we have termed the “Birmingham intervention tent technique (BITT).” This technique is ideal for biopsying osseous lesions where a direct approach is not possible due to difficult positioning.

Methods The BITT uses a plastic surgical forceps clamp attached at an angle to the biopsy needle, creating a tent shape. The finger rings of the forceps is stabilized on the table.

Results In our institution, we have already used the BITT successfully in over 10 cases.

Conclusion The BITT is an inexpensive and reproducible technique.

Surface adhesive and hand-aided needle-assisted biopsy technique (SAHNA)

OBJECTIVE

We describe a novel and efficient CT biopsy technique that we have termed 'skin adhesive and hand-aided biopsy technique', shortened to the acronym SAHNA. This technique is ideal for biopsying surface osseous lesions where there is a lack of subcutaneous fat. This avoids the need for the radiologist's hand to be in close proximity to the CT scanner beam at the time of intervention.

METHODS

The SAHNA technique uses a plastic surgical forceps towel clamp to stabilise the biopsy needle just proximal to the lesion after piercing through the skin. The clamp itself is stabilised via a self-adhesive dressing which is stuck down to the skin at its shank.

RESULTS

In our institution, we have already used the SAHNA technique successfully in over 5 cases.

CONCLUSION

The SAHNA technique is a widely accessible and effective way of stabilising the CT biopsy needle in technically challenging superficial bony lesions.
