Feb

Overview

Prostate imaging includes MRI ultrasound and nuclear techniques for detection and staging. Multiparametric MRI is central to lesion detection and biopsy guidance. Imaging supports treatment planning and surveillance.

Multiparametric MRI

mpMRI combines T2 diffusion and perfusion sequences for lesion characterization. It improves detection of clinically significant cancer and guides targeted biopsy. Standardized reporting systems aid communication.

PET Tracers

Prostate specific membrane antigen PET improves detection of recurrent and metastatic disease. PSMA PET complements MRI and conventional imaging in staging. Tracer availability and interpretation expertise influence use.

Biopsy Guidance

MRI ultrasound fusion and targeted biopsy improve diagnostic yield. Imaging guided biopsy reduces sampling error and overdiagnosis. Coordination with urology ensures appropriate management.

Abdominal CT

Feb

Overview

Abdominal CT provides detailed evaluation of organs and vasculature. It is used for trauma infection and oncologic staging. Contrast enhancement improves lesion detection.

Liver Imaging

CT characterizes liver lesions and assesses vascular anatomy. Multiphasic protocols improve detection of hepatocellular carcinoma. CT complements ultrasound and MRI in liver evaluation.

Bowel Imaging

CT enterography evaluates inflammatory bowel disease and small bowel tumors. It provides luminal and extraluminal assessment. Oral and IV contrast protocols optimize visualization.

Renal and Adrenal

CT assesses renal masses stones and adrenal lesions. It guides interventional procedures and surgical planning. Functional assessment may require additional imaging.

Oncology Imaging

Feb

Overview

Oncology imaging uses CT MRI PET and ultrasound for staging and surveillance. It assesses tumor extent nodal involvement and metastases. Imaging guides biopsy radiation and surgical planning.

Staging and Response

Imaging determines stage and evaluates treatment response over time. Serial imaging helps assess tumor shrinkage progression or recurrence. Standardized criteria improve consistency in reporting.

Therapy Planning

Imaging supports radiation planning surgical resection and interventional therapies. Functional imaging can identify viable tumor and treatment targets. Multidisciplinary review integrates imaging into care decisions.

Surveillance

Post treatment surveillance uses modality specific protocols to detect recurrence early. Imaging intervals depend on tumor type stage and risk factors. Coordination with oncology ensures appropriate follow up.

Imaging for Sarcoma

Feb

Overview

Imaging characterizes sarcoma extent grade and relation to neurovascular structures. MRI is the modality of choice for soft tissue sarcomas while CT assesses bone involvement and staging. Multimodality imaging informs biopsy planning and surgical margins.

MRI Protocols

High resolution MRI with contrast delineates tumor extent and involvement of adjacent structures. Functional sequences may provide additional information about tumor biology. Standardized reporting supports surgical planning.

Staging and Surveillance

CT chest is essential for pulmonary metastasis assessment in sarcoma staging. PET CT may detect occult metastatic disease in select histologies. Surveillance imaging intervals are tailored to histology and risk.

Interventional and Surgical Planning

Image guided biopsy ensures representative sampling for histologic diagnosis. Imaging guides limb salvage surgery and reconstructive planning. Multidisciplinary sarcoma teams integrate imaging into comprehensive care.

Imaging for Gynecologic Oncology

Feb

Overview

Imaging evaluates extent nodal involvement and metastatic disease in gynecologic malignancies. Modalities include ultrasound CT MRI and PET CT. Imaging guides surgical planning and adjuvant therapy decisions.

Pelvic MRI

MRI provides superior soft tissue contrast for local staging of cervical and endometrial cancers. It assesses tumor size parametrial invasion and nodal status. Standardized reporting improves multidisciplinary communication.

PET CT Role

PET CT detects nodal and distant metastatic disease in selected gynecologic cancers. It aids in recurrence detection and treatment planning. Tracer selection and timing influence sensitivity.

Surveillance and Recurrence

Imaging protocols for surveillance depend on tumor type stage and treatment. Early detection of recurrence may influence salvage therapy options. Multidisciplinary review ensures appropriate imaging intervals and modalities.

AI for Image Based Liver Fibrosis Staging
4
Feb

Overview

AI analyzes ultrasound CT and MRI features to stage liver fibrosis non invasively. Automated staging reduces need for biopsy in many patients. Quantitative outputs support monitoring and treatment decisions.

Techniques

Models use elastography metrics radiomic features and deep learning representations. Multimodal inputs improve staging accuracy. Calibration against histology validates performance.

Clinical Integration

Automated staging integrates with hepatology workflows for screening and management. Serial imaging tracks progression and response to therapy. Clear reporting supports clinical interpretation.

Limitations

Inflammation and congestion can confound imaging based staging. Local validation and awareness of confounders prevent misclassification. Multidisciplinary correlation improves diagnostic confidence.

Breast Lymphatic Drainage

Feb

Overview

Breast lymphatic drainage primarily flows to axillary lymph nodes and secondarily to internal mammary nodes influencing metastatic spread and staging. Lymphatic mapping identifies sentinel nodes for biopsy and treatment planning. Lymphatic anatomy guides surgical and radiation therapy decisions.

Axillary Nodal Levels

Axillary nodes are categorized into levels I II and III relative to the pectoralis minor and guide surgical dissection and staging. Nodal involvement impacts prognosis and adjuvant therapy selection. Imaging and sentinel node biopsy assess nodal status.

Internal Mammary and Supraclavicular Nodes

Internal mammary nodes lie along the internal thoracic vessels and supraclavicular nodes receive drainage from central pathways. Involvement of these nodes alters staging and radiation fields. Imaging and biopsy localize nodal disease for comprehensive care.

Clinical Relevance

Accurate nodal assessment is essential for breast cancer staging treatment planning and prognosis. Sentinel node biopsy imaging and PET guide management and reduce morbidity. Multidisciplinary oncology care tailors therapy to nodal status.
