Impact of radioguided occult lesion localization on the correct excision of malignant breast lesions: effect of histology and tumor size.

Aim: To evaluate the impact of radioguided occult lesion localization (ROLL) in the correct location and excision of malignant breast lesions, and analyze if these results are affected by the histology and tumor size.

Materials And Methods: A total of 105 patients with occult breast lesions were studied. The mean age was 55 years.

[PET-CT with intravenous contrast in the evaluation of patients with lymphoma. Contribution to diagnostic indications].

Aim: To define the utility of intravenous contrast administration in the PET-CT (PET-CTc) in patients with lymphoma in order to determine its possible indications.

Material And Methods: 78 patients with lymphoma were prospectively evaluated. All underwent simultaneous PET-CTc scans in a hybrid system for staging (8), evaluation of response to treatment (29), suspicion of recurrence (9) and complete remission control (48).

Pulmonary actinomycosis with thoracic soft tissue mass: a rare onset form.
