Concordance between preoperative imaging methods in patients with limb lymphedema undergoing supermicrosurgical lymphaticovenular anastomosis.

Objective: Supermicrosurgical lymphaticovenular anastomosis (LVA) is increasingly being recognized as a first-line treatment of limb lymphedema because it is minimally invasive and highly effective. Lymphoscintigraphy and indocyanine green (ICG) lymphography are the two most commonly performed diagnostic imaging examinations to establish the indication and plan the procedure for patients affected by limb lymphedema. In a small group of patients, the information between these two imaging tools can be discordant, showing different anatomical drainage pathways or the absence of drainage and dermal backflow in one examination and valid drainage pathways in the other.

Rest/Stress Intradermal Lymphoscintigraphy for the Functional Imaging of the Lymphatic System.

Purpose: Lymphoscintigraphy is the criterion-standard method for diagnosing lymphedema, and there is no universally standardized imaging modality. In our center, we use a new approach: rest/stress intradermal lymphoscintigraphy.

Methods: We tested 231 consecutive patients with suspected lymphedema.

A gravity-assisted approach to the management of urinary diversion: Tc-MAG3 diuresis renography with F + 10(sp) method.

Objective: Radical cystectomy with permanent urinary diversion is the gold standard treatment for invasive muscle bladder cancer. Hydronephrosis is common in these patients, but Ultrasound (US) or Computed Tomography Urography (CTU) scan are unable to discriminate obstructive from non-obstructive hydronephrosis. We used Diuresis Renography (DR) with F + 10 in seated position (sp) method in the identification of patients with a Uretero-ileal Anastomosis Stricture (UAS) who would benefit from surgical therapy.

Advantages of gravity-assisted diuretic renogram: F + 10 (seated position) method.

Introduction: In 1978, O'Reilly introduced the diuretic renogram using the F + 20 method. Initially, the patient was examined in the seated position. A dose of 40 mg furosemide was injected intravenously 20 min following tracer injection and dynamic acquisition was prolonged for 15-20 min.

Rest/stress intradermal lymphoscintigraphy in diagnosis of lipedema.

Lipedema is a chronic and progressive disease characterized by a symmetrical and bilateral swelling of the lower extremities. In general, the feet are not involved. Lipedema is believed to affect nearly 1 in 9 adult women worldwide.

SPECT/CT and fusion ultrasound to target the efferent groin lymph node for lymphatic surgery.

Introduction: Pelvic lymphadenectomy (PL) causes changes to the inguinal lymph nodes with progressive loss of immune and lymphatic pump function. Efferent lymphatic vessel-to-venous anastomosis (ELVA) has been reported to address this problem. The aim of this report was to describe the feasibility of the SPECT/CT combined with ultrasound fusion imaging (UFI) to target the groin efferent lymph node (GELN) for ELVA.

Intradermal-Stress-Lymphoscintigraphy in Early Detection and Clinical Management of Secondary Lymphedema: A Pictorial Essay.

Stress-lymphoscintigraphy evaluates the effects of exercise on lymph drainage. Results may predict outcomes of complex physical therapy as a first-line lymphedema treatment. Microsurgical approaches are best in patients with lymphangectasia or dermal backflow.

Radiomics in vulvar cancer: first clinical experience using F-FDG PET/CT images.

This study investigates whether radiomic features derived from preoperative positron emission tomography (PET) images could predict both tumor biology and prognosis in women with invasive squamous cell carcinoma of the vulva. Patients were retrospectively included when they had a unifocal primary cancer of ≥ 2.6 cm in diameter, had received a preoperative F-fluorodeoxyglucose (F-FDG) PET/computed tomography (CT) scan followed by surgery and had at least six months of follow-up data.

Lung uptake of fluorine-18 fluoroethyl-choline PET-CT in patients with prostate cancer.

Background: Metastatic spreading to the lungs is a negative prognostic factor in patients with prostate cancer (PC). Aim of our study was to assess the prevalence of lung PC metastases in patients with fluorine-18 fluoroethyl-choline (F-18-FECh) PET-CT positive lung lesions and the role of Gleason Score (GS) and common biochemical markers in predicting metastatic spreading to the lungs.

Methods: We retrospectively evaluated the scans of 1283 patients ongoing (F-18-FECh) PET-CT for PC between May 2010 and July 2014.

Evaluation of Dual-Timepoint F-FDG PET/CT Imaging for Lymph Node Staging in Vulvar Cancer.

This study aimed to assess the value of dual-timepoint F-FDG PET/CT in the prediction of lymph node (LN) status in patients with invasive vulvar cancer (VC) scheduled for inguinofemoral LN dissection. From April 2013 to July 2015, all consecutive patients with VC scheduled for inguinofemoral LN dissection were prospectively enrolled. All patients underwent a preoperative whole-body F-FDG PET/CT scan at 1 h (standard examination) and an additional scan from T11 to the groins at 3 h (delayed examination) after F-FDG injection.

Simultaneous total corporal reconstruction and implantation of a penile prosthesis in patients with erectile dysfunction and severe fibrosis of the corpora cavernosa.

Introduction: Implantation of a penile prosthesis in severely scarred corporal bodies represents a great challenge as fibrosis can compromise dilatation and subsequent closure of the corpora cavernosa and limit size, type, and function of the device.

Aim: The aim of this study is to report our experience of simultaneous corporeal reconstruction and penile prosthesis implantation in patients with severe penile contracture consequence of diffuse fibrosis.

Methods: Between March 2006 and February 2010, 18 patients with severe penile contracture and coporeal fibrosis underwent simultaneous corporeal reconstruction and placement of a penile prosthesis.
