Image-guided biopsy in primary lung cancer: Why, when and how

C. de Margerie-Mellon, C. de Bazelaire, E. de Kerviler

Diagnostic and Interventional Imaging > 2016 > 97 > 10 > 965-972

Initial histopathological analysis of a pulmonary lesion is mandatory whenever a lung cancer is suspected in order to determine the optimal diagnostic strategy. Adequate material must be obtained for a definite histological diagnosis (preferable to a cytological one) and in some cases (mainly in adenocarcinoma) molecular analysis. The two main methods to obtain adequate biopsy samples are flexible...

Diagnostic strategy for the assessment of axillary lymph node status in breast cancer

F. Maxwell, C. de Margerie Mellon, M. Bricout, E. Cauderlier, more

Diagnostic and Interventional Imaging > 2015 > 96 > 10 > 1089-1101

The nodal status in breast cancer is a major prognostic factor in terms of survival. It also plays a role in the therapeutic decision-making process. Therefore, the evaluation of lymph node involvement in breast cancer is imperative in establishing a personalized treatment scheme. The sentinel lymph node procedure has proved successful for small breast tumors (T1–T2), limiting axillary lymphadenectomy...

Biopsies in oncology

C. de Bazelaire, A. Coffin, S. Cohen, A. Scemama, more

Diagnostic and Interventional Imaging > 2014 > 95 > 7-8 > 647-657

Imaging-guided percutaneous biopsies in patients in oncology provide an accurate diagnosis of malignant tumors. Percutaneous biopsy results are improved by correct use of sampling procedures. The risks of percutaneous biopsy are low and its complications are generally moderate. These risks can be reduced using aids such as blund tip introducers, hydrodissection and correct patient positioning. The...

Correlation between MRI and biopsies under second look ultrasound

M. Nouri-Neuville, A. de Rocquancourt, S. Cohen-Zarade, M. Chapellier-Canaud, more

Diagnostic and Interventional Imaging > 2014 > 95 > 2 > 197-211

The term “second look” lesions in MRI refers to lesions detected by MRI that were not initially seen on mammography or ultrasound. The objectives of our study were to analyse the displacement of targets between MRI and ultrasound; to define discriminating BIRADS morphological criteria to predict benign or malignant character and better establish the indications of second look ultrasound and biopsy;...

Perfusion studies in senology

C. de Bazelaire, A. Scémama, A. Coffin, S. Cohen, more

Diagnostic and Interventional Imaging > 2013 > 94 > 12 > 1279-1290

Microcirculation imaging in breast cancer involves studying tissue enhancement after contrast injection, which is used to calculate perfusion and permeability. The magnitude of enhancement reflects blood and interstitial volumes. This technique has benefitted from advances in MRI, which allow large volumes to be acquired with a good compromise between temporal and spatial resolution. Software has...

Diffusion-weighted MR imaging of the breast: Advantages and pitfalls

I. Thomassin-Naggara, C. De Bazelaire, J. Chopier, M. Bazot, more

European Journal of Radiology > 2013 > 82 > 3 > 435-443

The aim of this paper is to review all clinical applications of diffusion weighted MR imaging (DWI) for breast pathology. The challenge of DWI is to obtain the best compromise between lesion detection and characterization. Technical factors affecting lesion characterization and detection are detailed including the effect of contrast administration, the choice of number of b and of b _max ,...

CT-guided biopsies in lung infections in patients with haematological malignancies

C. de Bazelaire, A. Coffin, S. Cohen-Zarade, C. de Margerie-Mellon, more

Diagnostic and Interventional Imaging > 2013 > 94 > 2 > 202-215

CT-guided transparietal lung biopsy in imaging makes it possible to find the pathogenic agent in half of all fungal infections and most bacterial infections (sensitivity=55%, specificity=100%). Performance is decreased in consolidations (50% of infections) compared to masses. Complications, pneumothorax, alveolar bleeding and hemoptysis are generally benign and rarely (<5%) require specific treatment...

Image-guided needle biopsy for diagnosis and molecular biology in lymphomas

E. de Kerviler, C. Benet, J. Brière, C. de Bazelaire

Best Practice & Research Clinical Haematology > 2012 > 25 > 1 > 29-39

Core needle biopsy is increasingly replacing excisional lymph node biopsy in the diagnosis and subclassification of malignant lymphomas, with obvious advantages in terms of morbidity and costs. This technique has radically altered the diagnostic strategy of enlarged lymph nodes at our institution, avoiding unnecessary nodal excisions. It represents a viable alternative as long as the number and size...

Breast inflammation: Indications for MRI and PET-CT

C. de Bazelaire, D. Groheux, M. Chapellier, F. Sabatier, more

Diagnostic and Interventional Imaging > 2012 > 93 > 2 > 104-115

Breast MRI should not be used for differential diagnosis between inflammatory breast cancer and acute mastitis (AM) prior to treatment. When mastitis symptoms persist after 10 to 15 days of well-managed medical treatment, MRI may be performed in addition to an ultrasound examination, a mammogram and to taking histological samples, in order to eliminate inflammatory breast cancer (IBC). For staging,...

Biopsies abdominales sous scanner

E. de Kerviler, C. de Bazelaire, P. Brunner, O. Mathieu, more

EMC - Radiologie > 2005 > 2 > 5 > 481-493

Les biopsies abdominales ont connu ces dernières années un essor spectaculaire grâce aux progrès des matériels de biopsie et des techniques de guidage (scanner et échographie), à une meilleure prise en charge des prélèvements en anatomopathologie, et surtout à une meilleure maîtrise des gestes interventionnels par les radiologues. Ainsi, de nombreuses lésions réputées difficiles d'accès ou dangereuses...

Reduced capillary perfusion and permeability in human tumour xenografts treated with the VEGF signalling inhibitor ZD4190: an in vivo assessment using dynamic MR imaging and macromolecular contrast media

C. Pradel, N. Siauve, G. Bruneteau, O. Clement, more

Magnetic Resonance Imaging > 2003 > 21 > 8 > 845-851

We describe the use of perfusion-permeability magnetic resonance imaging (ppMRI) to study hemodynamic parameters in human prostate tumor xenografts, following treatment with the vascular endothelial growth factor-A (VEGF) receptor tyrosine kinase inhibitor, ZD4190. Using a macromolecular contrast agent (P792), a fast MR imaging protocol and a compartmental data analysis, we were able to demonstrate...
