Digital breast tomosynthesis versus mammography and breast ultrasound: a multireader performance study.

Objectives: To compare the diagnostic performance of single-view breast tomosynthesis (BT) with that of dual-view mammography (MX); to assess the benefit of adding the craniocaudal (CC) mammographic view to BT, and of adding BT to MX plus breast ultrasound, considered to be the reference work-up.

Methods: One hundred and fifty-five consenting patients with unresolved mammographic and/or ultrasound findings or breast symptoms underwent conventional work-up plus mediolateral oblique-view BT of the affected breast. The final study set in 130 patients resulted in 55 malignant and 76 benign and normal cases.

Ultrasound elastography as an objective diagnostic measurement tool for lymphoedema of the treated breast in breast cancer patients following breast conserving surgery and radiotherapy.

BACKGROUND.: Lymphoedema of the operated and irradiated breast is a common complication following early breast cancer treatment. There is no consensus on objective diagnostic criteria and standard measurement tools.

Initial axillary staging of breast cancer using ultrasound-guided fine needle aspiration: a liquid-based cytology study.

Objective: To evaluate the preoperative detection of axillary metastasis combining ultrasound (US)-guided fine needle aspiration cytology (FNAC) and liquid-based cytology (Surepath(®)) to reduce sentinel node procedures.

Methods: In total, 148 patients with clinically negative lymph nodes and no preoperative therapy were included. All patients underwent preoperative ultrasound of the axilla with FNAC if suspicious lymph nodes were found.

Development of a multi-spectral, multi-geometry computational model for X-ray breast imaging.

The introduction of novel applications in X-ray breast imaging warrants new research for image acquisition optimisation. A simulation model was developed to investigate the influence of different imaging techniques and acquisition parameters. It was modelled in Monte Carlo N-Particle Extended and contains an X-ray tube with photon production, a breast model and antiscatter grid model.

Rupture of renal artery aneurysm into the renal pelvis, clinically mimicking renal colic: diagnosis with multidetector CT.

We report on a 60-year-old man, seen at the emergency department because of severe left flank pain. Clinical diagnosis was that of renal colic. Overnight he became haemodynamically unstable and haematuria became massive, so multidetector CT (MDCT) was performed.

Granulomatous lobular mastitis: a rare chronic inflammatory disease of the breast which can mimic breast carcinoma.

Granulomatous lobular mastitis is a rare chronic inflammatory disease of the breast. The differential diagnosis with malign breast disease is often not easy. In most cases a surgical biopsy is needed for correct diagnosis.

Prevalence of annular tears and disc herniations on MR images of the cervical spine in symptom free volunteers.

Study Design: Prospective MR analysis of the cervical spine of 30 asymptomatic volunteers.

Objectives: To evaluate the prevalence of annular tears, bulging discs, disc herniations and medullary compression on T2-weighted and gadolinium-enhanced T1-weighted magnetic resonance (MR) images of the cervical spine in symptom free volunteers.

Summary Of Background Data: Few studies have reported the prevalence of cervical disc herniations in asymptomatic people, none have reported the prevalence of cervical annular tears on MR images of symptom free volunteers.

Bilateral breast masses in a young pregnant woman.

Although uncommon, breast metastases from malignant extramammary lesions are important in the differential diagnosis of breast lesions. We report a case of malignant melanoma with bilateral breast metastases in a young pregnant women.

Use of diffusion-weighted MR imaging in differential diagnosis between intracerebral necrotic tumors and cerebral abscesses.

The differential diagnosis between intracerebral necrotic tumors and cerebral abscesses is frequently impossible with conventional MR imaging. We report two cases of cerebral abscesses that showed high signal on diffusion-weighted echo planar imaging and a strongly reduced apparent diffusion coefficient. This appearance was not present in our cases of necrotic/cystic gliomas (eight cases) and necrotic metastases (two cases).

Ultrasound studies in ectopic pregnancies.

Early diagnosis of ectopic pregnancy reduces the mortality and morbidity associated with the disease, and the morbidity associated with the therapy. When diagnosis was limited to the cases presenting with tubal rupture, salpingectomy was the only possible treatment. If ectopic pregnancy can be diagnosed earlier, clinicians are able to use new therapies such as laparoscopic microsurgery or medical therapy with methrotrexate, which are less invasive and less tissue destructive.
