Towards a real-time assessment of microbiopsies with Light-CT
Limits of core needle biopsies Kidney needle biopsy – CT scan  guidance Suspicion of tumorous  lesion / necrosis Breast needle biopsy – Ultrasound image guidance Small nodule (~5mm) Lesion hidden by the needle 5-10% of useless material due to a wrong biopsy location >> re-operation following histology (after a few days) Is Light-CT a good tool for peroperative assessment of microbiopsies ?
A first example: kidney 2x8mm 14 gauge : Inner/Outer diameter:1.6/ 2mm  100µm 100µm 50µm

Fibroadenoma Fibrous and adipous border is clearly visible. Acini can be differentiated from surrounding stroma.  Suspicion of benign lesion. 80µm

Invasive lobular breast carcinoma 500µm 300µm
Infiltrative breast carcinoma ,[object Object],100µm 150µm

The imaging technique has potential to be used to assess the needle core biopsies  ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],The technique is a new tool for clinicians requiring a fast tissue  assessment in order to avoid standard time-consuming, expensive  pathology exams => Regarding microbiopsies, it has the potential to be used by radiologists  in order to : avoid repetition  of core needle biopsies evaluate the relevance of tissue for further molecular analysis
