Gamma Probe for Sentinel Lymph Node BiopsyEuroprobe™ 3.2 — Intraoperative Gamma Detection for SLN + Radio-Guided Surgery
Intraoperative gamma probe for sentinel lymph node biopsy (SLN) and radio-guided surgery — one handheld console with two scintillator families (CdTe and CsI(Tl)) and 28+ probe geometries. The gamma probe is used to localise the sentinel lymph node in early breast cancer, cutaneous melanoma, cervical, endometrial, vulvar, penile, oral-cavity, prostate and bladder cancers; for radio-guided occult-lesion localisation (ROLL) after I-125 seed implant; for parathyroid adenoma surgery after Tc-99m-MIBI; and for I-131 thyroid-remnant and F-18 radio-guided oncological workflows. CdTe delivers high-sensitivity 20–170 keV coverage (Tc-99m, I-125); CsI(Tl) extends coverage to 100 keV – 1 MeV (I-131 at 364 keV, F-18 at 511 keV). Straight, curved, collimated, laparoscopic (frontal / lateral / 45°) and wireless Bluetooth probes picked per case from the same console. Distributed, installed, trained and serviced across India by Saxsons Healthcare — India's trusted gamma probe supplier since 1988.
Key Features
- Single console + 28+ probe models — one investment covers every SLN and radio-guided workflow the OR team runs
- CdTe scintillator family — high-sensitivity at the Tc-99m (140 keV) and I-125 (27 keV) workhorse range; optimum 20–170 keV
- CsI(Tl) scintillator family — extends coverage to I-131 (364 keV) and F-18 (511 keV with collimator); 100 keV – 1 MeV

Applications
Sentinel-node biopsy across breast, melanoma, gynae, urology, ENT — plus ROLL, parathyroid, and selected I-131 / F-18 workflows
Breast SLN biopsy
Tc-99m-nanocolloid / Tc-99m-tilmanocept pre-injection; 6–14 mm CdTe straight or collimated probe; intraoperative axillary node localisation and excision. Collimated probe variants discriminate against the peri-areolar injection-site hot spot.
Melanoma SLN biopsy
Tc-99m-nanocolloid intradermal injection at the primary site; CdTe 11 / 14 mm probe across axillary, inguinal, popliteal, head-and-neck and intransit basins. The cutaneous workflow is the foundational gamma-probe indication.
Gynaecological SLN (cervix, endometrium, vulva)
Open or laparoscopic / robotic SLN across the cervical, endometrial and vulvar cancer pathway. Laparoscopic frontal / lateral / 45° probe variants reach the obturator and external iliac stations through standard trocars.
Penile / urological SLN
Penile cancer inguinal SLN biopsy; selected prostate / bladder cancer protocols. CdTe sensitivity profile matches the typical 30–60 MBq Tc-99m colloid injection.
Head & neck SLN (oral cavity, larynx)
Oral SCC and selected laryngeal cases; the curved probe geometry tracks the floor-of-mouth and submandibular drainage pattern.
Radio-guided occult-lesion localisation (ROLL)
I-125 seed pre-implant for non-palpable breast lesions or soft-tissue masses; the CdTe probe at 27 keV gives clean directional read-out for image-guided excision without intraoperative wire dislodgement risk.
Parathyroid surgery
Tc-99m-MIBI pre-injection on the morning of surgery; collimated CdTe probe localises hyperfunctioning adenoma intraoperatively when the pre-op SPECT-CT is equivocal.
Thyroid-remnant / metastasis (I-131)
CsI(Tl) probe at 364 keV for selected recurrent-thyroid-carcinoma surgery — intraoperative localisation of cervical-nodal disease previously identified on diagnostic I-131 scan.
Radio-guided occult-lesion with F-18 PET tracer
Selected protocols with pre-op F-18-FDG-PET-positive lesions — CsI(Tl) probe with collimator for 511 keV annihilation read-out under tight directional discrimination.
Why Gamma Probe for Sentinel Lymph Node Biopsy?
CdTe covers the high-sensitivity workhorse range (Tc-99m at 140 keV, I-125 at 27 keV); CsI(Tl) extends to I-131 at 364 keV and F-18 at 511 keV. One console runs both — the OR avoids the multi-platform cost when the radiology and theranostic workflows want different energy windows.
Maximum count rate of 30 000 cps handles the hot-spot near the injection site, the bulk-activity ROLL workflow and the high-activity I-131 thyroid case without saturation — the surgeon trusts the count even when the geometry is unfavourable.
Straight, curved, collimated, laparoscopic (frontal / lateral / 45°) and wireless Bluetooth variants from the same console. Pick the geometry per case — the open breast SLN, the laparoscopic gyn-onc pelvic SLN, the ENT floor-of-mouth — without buying a second platform.

FAQ
Gamma probe, sentinel lymph node biopsy, radio-guided surgery — questions we hear from Indian surgical-oncology teams
What a gamma probe does in the operating theatre, which cancers it is used for, which isotopes it supports, the CdTe-vs-CsI(Tl) trade-off and how the Europrobe 3.2 gamma probe is supported in India.
Q.What is a gamma probe used for in surgery?
A gamma probe is a handheld intraoperative detector that finds tissue containing a small amount of a radioactive tracer. The most common use is sentinel lymph node biopsy (SLN) in breast cancer, melanoma and gynaecological cancers: the patient receives a Tc-99m radiopharmaceutical before surgery, the tracer drains to the first (sentinel) lymph node in the tumour’s drainage basin, and the surgeon uses the gamma probe intraoperatively to localise and excise that node with millimetre precision. Gamma probes are also used for radio-guided occult-lesion localisation (ROLL), parathyroid adenoma surgery, thyroid-remnant surgery (I-131) and selected F-18 radio-guided cases.
Q.Which cancers use gamma-probe-guided sentinel lymph node biopsy?
Sentinel lymph node biopsy with a gamma probe is standard of care for early breast cancer (NSABP B-32, Krag 2010), intermediate-thickness cutaneous melanoma (MSLT-I / MSLT-II, Morton 2014 / Faries 2017), vulvar cancer (GROINSS-V, Van der Zee 2008) and endometrial cancer (SENTI-ENDO, Ballester 2011). Cervical, penile, oral-cavity, laryngeal, prostate and bladder SLN protocols are established in the literature and use the same probe families. The Europrobe 3.2 supports every one of these indications from a single console.
Q.Which isotopes does the Europrobe 3.2 gamma probe support?
Tc-99m (140 keV — the workhorse SLN isotope), I-125 (27–35 keV — ROLL for non-palpable breast lesions), In-111 (171 / 245 keV — lymphoscintigraphy), I-131 (364 keV — thyroid-remnant / metastasis) and F-18 (511 keV — PET-tracer radio-guided occult-lesion localisation, with the collimated CsI(Tl) probe). Each isotope has a pre-set energy window on the console — no manual calibration in theatre.
Q.What is the difference between the CdTe and CsI(Tl) gamma probes?
CdTe (cadmium telluride) is a semiconductor scintillator with peak sensitivity at 20–170 keV — the optimum range for Tc-99m and I-125. Use CdTe for routine breast, melanoma, gynae, ENT, urology SLN and for I-125 seed ROLL. CsI(Tl) (thallium-doped caesium iodide) is a heavier crystal scintillator with useful sensitivity from 100 keV to 1 MeV — the choice for I-131 thyroid-remnant surgery (364 keV) and F-18 radio-guided occult-lesion localisation (511 keV). The Europrobe 3.2 runs both scintillator families from the same console.
Q.Can the Europrobe gamma probe be used for laparoscopic and robotic surgery?
Yes. The Europrobe 3.2 laparoscopic probe series (SOE 3215 frontal / SOE 3215-L lateral / SOE 3215-45 at 45°) passes through standard 10 mm trocars and reaches obturator, external iliac and pre-sacral SLN stations in gynae-oncology and urology robotic / laparoscopic workflows. The wireless Bluetooth CdTe-BT and CsI-BT variants keep the OR ergonomics cable-free.
