Leading-edge technology

The American Hospital of Paris is equipped with one of the ten most advanced mammography systems in the world. Digital breast tomosynthesis (3D imaging method) offers better viewing, which in turn leads to more accurate diagnoses. All supplementary exams can be performed on site on very short notice, including MRI, microbiopsy and macrobiopsy testing.


One of the most important technological advances in recent years is breast tomosynthesis.

This 3D mammography technique consists in moving the x-ray tube around the breast to capture multiple images at the same time, as opposed to a single image captured with traditional mammography.

The images are reconstructed, or synthesized, using an algorithm similar to the one used by a CT scan. This technology facilitates the detection of early-stage cancer in a normal mammary gland, and makes it easier to distinguish dense, fibrous breast tissue which could lead to a false-positive.

A large study involving 200,000 women showed a nearly 30 percent relative increase in the number of cancers detected using this technique.

 The American Hospital of Paris has acquired a new latest-generation 3D mammography device. Its rounded angles and reassuring design in pastel pink and white tones help to create a more user-friendly and less stressful experience for patients. The device’s technical features are also as discrete as possible, eliminating an additional stress factor for women.

With this system, the technician begins compressing the breast as usual, then gives the patient a remote control device which she can then use (if she wishes) to continue compressing her breast. This enables her to play an active role in the exam while improving her tolerance for this step of the procedure.

Our new breast tomosynthesis device is part of our comprehensive approach to personalized patient care, provided by dedicated radiologists and technicians.



This pain-free exam, which uses high frequency sound waves instead of x-rays, is performed at the discretion of the radiologist after a screening mammogram.

It is particularly recommended when dense breasts are revealed by the mammogram, or to investigate or rule out an abnormality detected on the mammogram.

At the American Hospital of Paris, we use a latest-generation ultrasound device exclusively dedicated to breast exams. Because the images are produced approximately 200 times faster than with conventional ultrasound systems, they are exceptionally high-quality, homogenous, high-definition and informative.

We also use elastography to view and analyze tissue “stiffness” in real time. Tissue stiffness has become a very important parameter in ultrasound imaging for the diagnosis of potentially malignant lesions.

This parameter is now used in international classifications of breast abnormalities and is said to help reduce the number of unnecessary biopsies.

Breast MRI

This exam takes about fifteen minutes and requires no radiation. Instead, an iodinated contrast agent, well-tolerated by patients, is injected.

MRI is the gold standard for detecting breast cancer in very high-risk patients (those with an inherited gene mutation or who underwent chest radiation for hematologic disease between the ages of 10 and 30).

This exam is also indicated for women diagnosed with breast cancer before the age of 40, to assess certain types of breast cancer or in the case of specific treatments such as preoperative chemotherapy. Lastly, it can be used to determine whether a breast implant has ruptured.

MRI will probably play an increasingly crucial role in indications that are currently still under debate, such as pre-operative assessments for non-locally advanced breast cancers. Some recent studies have shown that the rate of revision surgery (when a second surgical procedure is necessary) was divided in half in patients having undergone a systematic preoperative MRI.

When breast cancer is discovered in a patient with high mammographic breast density, which can “mask” a cancerous lesion, an MRI might also be performed to search for other abnormalities that cannot be detected with a mammogram.
Unless it is being employed as part of the proven strategy of regularly monitoring very high-risk patients (with an identified genetic risk), an MRI is often performed as a second-line exam whose results must be analyzed in combination with all other exams performed.


Elle regroupe toutes les pratiques visant à établir un diagnostic histologique (au microscope) ou à préparer le geste opératoire du chirurgien en cas d’intervention.

Grâce à nos appareils de plus en plus sophistiqués nous détectons des lésions de plus en plus petites et non palpables par la patiente ou son médecin.
Pour les analyser on utilise la technique de prélèvements (cytoponctions, microbiopsies et macrobiopsies). Ces gestes sont guidés sous échographie, avec l’appareil de Mammographie et même parfois sous IRM.

Les cytoponctions avec une aiguille fine, sont réservés à l’étude des ganglions ou à l’évacuation d’un kyste gênant ou douloureux.
Les microbiopsies sont utilisées en échographie pour analyser une masse. La patiente est allongée sur la table d’échographie et après désinfection et anesthésie locale, on réalise le prélèvement qui sera adressé au laboratoire pour analyse microscopique.

Les macrobiopsies peuvent être utilisées indifféremment en échographie, mammographie ou IRM. Elles sont le plus souvent utilisées avec un guidage mammographique pour analyser des microcalcifications découvertes en Mammographie. Avec notre tout nouveau système, la patiente est en position assise, allongée ou semi-allongée, le sein est comprimé, centré sur la zone des calcifications et après désinfection et anesthésie locale, les prélèvements sont réalisés de façon automatisées avec un appareil dédié de dernière génération. On peut aussi réaliser aujourd’hui des biopsies sous tomosynthèse 3D. Après ces prélèvements on laisse en place un clip (un tout petit repère en titane), qui servira pour le repérage préopératoire en cas d’indication chirurgicale. Si la lésion est bénigne, grâce à cette technique sous anesthésie locale, en ambulatoire et sans hospitalisation, on aura évité à la patiente un geste chirurgical.

Le repérage préopératoire a pour but d’aider le chirurgien à prélever une lésion non palpable. Le geste est réalisé en général dans les 24heures au plus avant l’acte chirurgical, en introduisant dans le sein, après désinfection et anesthésie locale, un fil guide au centre de la lésion, en se guidant en mammographie (microcalcifications) ou échographie (masse).
