Median lobe of prostate ultrasound the frequent use of computed tomography, carotid ultrasound studies and positron emission scans nowadays, many small, non-palpable thyroid nodules are incidentally detected.
The use of high intensity focused ultrasound MRI guided or ultrasound guided have been used to treat different types of soft tissue cancer like prostate cancer, liver cancer and breast cancer.
This device has been tried in a clinical study where patients with thyroid nodules, who were already scheduled for thyroidectomy, were treated using HIFU in order to evaluate the safety and feasibility of the device and to better determine the treatment parameters and effect.
Cancer benign tissue
The results showed that the overall safety of the treatment was satisfactory and the lesions produced by the HIFU shots in the nodule were precise. This pilot study was extended to a clinical trial where patients with a benign thyroid nodule were treated. Twenty-one patients were treated in this study versus 11 controls. No serious adverse events SAE have occurred.
The treatment median lobe of prostate ultrasound well tolerated and biologic euthyroidism was achieved at 3 months TSH, 1.

At 12 and 18 months, the treated nodule was barely seen as a nonvascularized hypoechoic scar. Thyroid scintigraphy showed a recovery of the thyroid iodine uptake.
The mean follow-up is 9. Symptomatic hypocalcaemia was not observed in any patient after HIFU treatments or during follow-up. Twenty thyroid nodules were treated during one HIFU session. The mean ± standard deviation nodule volume was 4.

Nodule volume had decreased to 3. By then, the mean volume reduction was Minor transient complications such as subcutaneous edema and mild skin redness were observed in two patients. Another monocenter study was performed in Germany in Ten patients with one thyroid nodule each were treated by HIFU.
Three months after the procedure, thyroid nodule volume was significantly reduced by In terms of safety, no serious side effect related to the procedure was reported. Objectives: The present study is aimed to explore the followings: 1. To evaluate the efficacy of the HIFU for the treatment of benign thyroid nodules using assessment of patient experience and adverse event reporting.
To evaluate the tolerance of HIFU in the treatment of benign thyroid nodules. To determine the location parameters associated with optimal efficiency tissue ablation. The procedure schedule comprises:.
