Pain Is Not Your Routine.
It’s a Signal. And There Is a Solution.
Beyond what conventional exams can see.
Tractography •
_edited.png)
We reach where conventional
MRI and CT scans cannot.
Have you been feeling pain
for months or years?
Have you undergone several tests but still haven't found answers?
Do you have pain in your lower back, pelvis, sciatica, hips, or limbs?
Pain is not normal. Don’t accept living like this.
It’s a sign that your body needs to be heard, understood, and treated.
High-Precision Diagnosis for Chronic Pain
Here, we use advanced magnetic resonance neurography and tractography exams, capable of accurately identifying:
Hidden neuropathies
Nerve compressions
Neurovascular conflicts
Alterations of the lumbosacral, pelvic, and pudendal plexuses
Stop treating just the symptoms.
Find the Solution.
My
specializations
Peripheral Nerve Neurography and Tractography by Magnetic Resonance Imaging
Advanced and highly specialized exams capable of detecting subtle changes in peripheral nerves and neural plexuses that are not visible in conventional exams.
Indications
Brachial Plexus
Sacral
Plexus
Peripheral Neuropathies
Chronic pain, neuropathies, deep endometriosis, neurological deficits, and postoperative conditions.
Lumbosacral Plexus
Pelvic
Plexus
Multiparametric Prostate MRI and
MRI–Ultrasound Fusion Biopsy
Advanced prostate cancer diagnosis with high accuracy, sensitivity to clinically significant lesions, and reduced need for unnecessary biopsies.
Advantages
Detailed evaluation using the PIRADS protocol
Biopsy guidance with automatic MRI-US fusion
Specialized
second opinion
Recommended for screening, second opinions, or complex cases
No pain
is ok.
In many cases, the limitations of conventional exams prevent doctors from reaching an accurate diagnosis.
A diagnosis requires solid evidence. That’s what we deliver: absolute precision and unwavering confidence.
If the source of your pain is still a
mystery, we will uncover it with you.

Why choose
Dr. Samir Nassar
Years of experience in diagnosing musculoskeletal and neuropathic pain.
Focused on collaborating with your physician to find the best path for your treatment.
Prostate Image and Fusion Biopsy
Fusion biopsy combines MRI and ultrasound to accurately locate suspicious areas. Less uncertainty, more confidence.
Indicações clínicas
A biópsia com fusão utiliza as imagens da ressonância e ultrassom para guiar a coleta com exatidão. Indicada em casos de aumento do PSA ou da próstata, oferece precisão superior à biópsia tradicional.
Orientações
O preparo é passado em consulta e inclui jejum e limpeza intestinal. O exame é feito com sedação, por isso é obrigatório comparecer com acompanhante no dia agendado.
Musculoskeletal
System Imaging
Imaging diagnosis detects lesions, inflammations, and changes with high definition. Greater clarity in treatment, less uncertainty for the patient.
Indicações clínicas
A imagem do sistema musculoesquelético é indicada para a investigação de dores articulares lesões em músculos tendões e articulações além de alterações na coluna pelve ou quadril sendo útil também no acompanhamento de lesões esportivas ou no pós-operatório.
Orientações
O exame é feito por ressonância magnética e dura em média 20 minutos. Pode exigir jejum de 3 horas e, em alguns casos, preparo intestinal. Todas as orientações são passadas previamente pela equipe.
Neurotractography
Exam
Neurotractography allows high-precision visualization of neural networks, significantly contributing to complex neurological diagnoses.
Indicações clínicas
A neurotractografia por ressonância é indicada para avaliar alterações em nervos profundos que não são visíveis em exames convencionais sendo especialmente útil em casos de dores crônicas sem causa definida suspeitas neurológicas síndromes compressivas como ciática ou piriforme e no planejamento cirúrgico de maior precisão.
Orientações
O exame dura cerca de 1 hora e exige jejum de 3h. Pode haver preparo intestinal, dependendo do caso. É necessário preencher um formulário para personalizar o protocolo conforme sua necessidade.
